Liberty Workbench is an occasional series where I put one idea on the bench and think it through with you.

Quick recap of the story that was everywhere last week. 📰 Then the good part that sent me down a rabbit hole: that little 'Thinking' box, and how wrong I was.

OpenAI was testing a combination of its models on a cybersecurity benchmark called ExploitGym, including GPT-5.6 Sol and a more capable model that hasn’t been released yet (GPT-6..?). The usual safety refusals around hacking had been dialed down so OpenAI could measure their maximum cyber capabilities.

The models went looking for the answer key. 🔑

They found a previously unknown vulnerability in the one piece of software their sandbox was allowed to talk to, and used it to get out. Once they had internet access, they figured Hugging Face probably hosted the solutions to the benchmark. So they broke into Hugging Face’s production systems and took the answers. 🔓

Nobody told them to escape the evaluation environment or access Hugging Face. The instruction was to solve the benchmark.

Hugging Face disclosed the intrusion on July 16, without knowing who was behind it. Five days later, OpenAI disclosed that its own models were responsible.

Five Cheaters

On July 21, the same day as OpenAI’s disclosure, UK AISI published its findings on cheating in cyber evaluations. They tested five recent frontier models from OpenAI and Anthropic for cheating behavior (GPT-5.4, GPT-5.5, GPT-5.6 Sol, Claude Opus 4.7, and Claude Mythos Preview).

*Every* one of them attempted to cheat. 5/5.

But weren’t they just asked to cheat? Nope, the models weren’t prompted to do it. Just to solve a test.

Then one evaluation was accidentally misconfigured and impossible to solve. The model wouldn’t give up. It wrote and ran code on an external service, using it to try to reach back into AISI’s own evaluation infrastructure. It looped through the open internet to go after the teacher administering the test.

It was the same basic move as the Hugging Face incident: go after the machinery around the test when you can’t solve the test itself. Nothing was exfiltrated. It only stayed a footnote because AISI’s security held.

Successful Cheating is Invisible (by definition)

The cases making headlines or showing up in papers are the ones we caught. But what if there’s successful cheating? It would be invisible, and because the goal of cheating is to increase benchmark scores, it would only move results in one direction.

We already know models can cheat because we caught them doing it. If nobody carefully checked an agentic benchmark for cheating, its score could be too high by an unknown amount. And that’s before benchmaxxing, test sets accidentally leaking into training data, and human-directed cheating.

AISI says that, as far as it knows, no model has successfully cheated in its published results, where “successfully” means it wasn’t caught. That’s the only sensible definition.

I give them credit for doing the expensive thing. AISI manually reviews the transcripts from every published capability evaluation to make sure cheating hasn’t inflated the numbers.

But it still leaves us with a pretty circular sentence.

Basically: we haven’t caught any cheating we didn’t catch. 🔄 😅

Whatever rate AISI detects is a lower bound. We don’t know how much was missed, but any successful cheating that was missed would bias the capability score upward.

BUT

They say themselves that this doesn’t scale. Manual review is slow, and as deployment cycles speed up, outside evaluators face more pressure to keep up.

And even then, it doesn’t always work.

Normally, the thing you’re measuring can’t touch your measuring device. The weather can’t hack the thermometer. The bacteria can’t mess with the microscope 🔬

AISI’s own example: cheating made METR’s evaluation of GPT-5.6 Sol impossible to measure robustly. METR tried three ways of handling the attempts and didn’t consider any of the resulting numbers reliable. METR is one of the independent outfits labs hand their models to before release. This time, the thing being measured reached over and started messing with how the referee kept score.

How would you ever find out?

This may seem like an easy question to answer. Just check the logs, right?

Reuters reported:

“It was not until after Thursday, July 16, when Hugging Face published a blog post saying it had been hacked by ‘an autonomous AI agent system,’ that OpenAI realized its own agent was responsible.”

It looks like OpenAI found out from its victim, at least a week after the model first showed signs of troubling behavior.

OpenAI employees later found clues in the internal logs. The problem is scale. Reuters says OpenAI often runs several high-speed evaluations at once, generating “such enormous amounts of data that employees sometimes struggle to keep up.”

Once you know there’s a needle in the haystack (🪡), it’s much easier to go looking for it. Without Hugging Face’s post, the evidence was somewhere inside a mountain of hay logs, and nobody knew there was a problem to look for. We don’t know when, or even IF, OpenAI would have found it. 🕵️‍♂️

AISI faces the same problem on the evaluator side: reviewing transcripts by hand doesn’t scale, especially as deployment cycles speed up.

There’s another place to look, though: a very strange measuring device produced by the thing we’re trying to measure. On top of the logs of what the model did, we can also look at what it was thinking. 🤖💭

Since o1, frontier LLMs have come with a little expandable ‘Thinking’ line that you can look into with one click.

What’s Actually in the Box?

The next obvious place to look for signs of cheating is that chain-of-thought box. If the model is cheating, you should be able to open it and catch the model red-handed, right?

That’s what I thought, anyway.

I assumed the box was a log: a record of the steps the model took to get to an answer it couldn’t produce in one shot, written down as it went. It says ‘Thinking’ on the label and it’s full of sentences that read like someone working through a problem… so what else would it be? 📦🏷️

But AISI found that models often cheated without explicitly discussing what they were doing in the chain of thought. In the case of Claude Opus 4.7, the model rarely produced a reasoning trace for the specific action that AISI classified as cheating.

Anthropic found something similar in a 2025 study. They compared reasoning models Claude 3.7 Sonnet and DeepSeek R1 with two non-reasoning models from the same families. When the researchers slipped hints into a problem that influenced the models’ answers, across six different kinds of hints, Claude mentioned the hint just 25% of the time and DeepSeek 39% of the time.

Then they pushed it further. They fine-tuned an earlier snapshot of Claude 3.7 Sonnet to exploit hidden shortcuts that rewarded it for giving factually wrong answers. It learned to take the shortcut on more than 99% of examples. But in five of the six test environments, the hack appeared in its chain of thought on fewer than 2% of examples. Sometimes the trace jumped to the wrong answer without explaining the switch. Sometimes it made up a perfectly plausible explanation for why the wrong answer was actually right.

One caveat: this was an artificial multiple-choice setup where Claude didn’t need to use its chain of thought to take the shortcut, so 2% is not a general rate for how often models reveal cheating.

The reward hack that drove the switch never appeared in the chain of thought.

But what you see depends on the product. ChatGPT shows a model-generated summary rather than the raw trace. Anthropic has sometimes shown Claude’s raw thinking and sometimes summarized it. Outside evaluators don’t always get full access either. AISI couldn’t include GPT-5.4 or GPT-5.5 in its chain-of-thought analysis for that reason.

The raw trace is still part of the real process. The model generates those intermediate tokens while working through the problem, and they can help produce the answer. But they aren’t a complete transcript of everything that caused it.

There’s a loose analogy to human brains: plenty goes on in our noggins without ever becoming words. A transcript of our inner monologue would reveal a lot, but not everything. 🧠

So even the raw trace in the box can fail in two ways. It can leave out the thing that actually changed the answer, or add plausible explanations that weren’t the real reason.

A Fragile Opportunity

Yeah, so far, the thinking box isn’t looking great. AI researchers have found that it can leave things out, make things up, and look all innocent and normal while the model cheats.

But you don’t have to see everything for it to be useful.

Because sometimes the model writes the incriminating part down ✍️

Researchers have found chain-of-thought traces containing lines like ‘Let’s hack’ and ‘Let’s sabotage.’ That can help catch behavior you might miss by looking only at the model’s actions or final answer.

That’s called chain-of-thought monitorability. 🤖📃🔍

Last July, 41 researchers from across the major AI labs and safety organizations published a paper that calls it ‘a new and fragile opportunity for AI safety.’

They say it works for two reasons:

1. Necessity is when a task is complicated enough that the model has to use the chain of thought as a scratchpad.

2. Propensity is when the model doesn’t need to write something down, but happens to think out loud anyway.

That’s why Anthropic’s 2% result doesn’t tell us all we need to know. Its shortcuts were simple enough that Claude didn’t need the chain of thought to use them. METR made the clues complicated enough that models had to work through them in the scratchpad:

When we examined 21,272 trajectories where the clues were complex enough that models couldn’t make use of them without CoT, we were only able to find three where any model plausibly failed both to show the steps of its reasoning and to mention it was using the clue in its CoT. (And for the three trajectories that were plausibly unfaithful, it’s possible our ground truth labels were wrong.)

A simple shortcut can happen outside the scratchpad. A complicated plan that needs the scratchpad is more likely to leave tracks.

OpenAI later ran 13 monitorability evaluations across 24 environments and found that “most frontier reasoning models are fairly monitorable, though not perfectly so.” In almost every setting, reading the chain of thought worked substantially better than watching only the model’s actions and final answer.

OpenAI also studied two frontier reinforcement-learning runs. At current scales, more training did not meaningfully reduce monitorability. That’s encouraging.

The thinking box can catch a surprising amount. But seeing the cheating is not the same as stopping it.

In one of OpenAI’s worked examples, a model wrote: “But monkey patching time within solution is arguably cheating… Acceptable.”

If We Don’t Mess It Up

Right now, models are terrible at keeping their mouths shut.

OpenAI gave GPT-5.2 a simple instruction: solve the problem without using the word ‘XOR’ in its chain of thought. The model used it, noticed its mistake, and wrote: ‘Oops I wrote “XOR” in analysis already.’

Then it used the word four more times.

6️⃣🎂🗓️🚢 Monday, July 20th, 2026, was the sixth anniversary of this here place.

Has it been 72 months already? 2,191 days? 52,600 hours? 3.15 million minutes? (ok, I’m stopping now)

When I started going clickety-clack on my keyboard, my oldest boy was 6yo, and my youngest was 2yo. As Dave Chappelle once said, I see my age in my children. I also see my age in this project.

You can’t live through all those minutes without changing.

It’s the old Heraclitean idea: No man ever steps in the same river twice, for it's not the same river and he's not the same man. And creating 640+ Editions does leave a mark (almost 700 if you count the podcasts, text interviews, and now Workbench issues…). My fingers may be callused from playing guitar, but after six years, my brain feels callused by this project (hopefully the good kind that allows you to play better and faster, but you be the judge of that 😅).

I recently came back from a family vacation. We went to Sandbanks Provincial Park in Prince Edward County, Ontario (🇨🇦). It has long, beautiful sand beaches on the shores of Lake Ontario and the largest baymouth barrier dune formation in the world.

A few days before we went, I watched Dune 1 & 2 with my oldest boy, so we kept making jokes about sandworms and Fremen popping out of the dunes. Just two nerds!

Ironically, I was extremely productive during my vacation. I can’t help it. When I have time to think, I have lots and lots of ideas ¯\_(ツ)_/¯

So I spent my days doing stuff with my family, or reading a book in the shade at the beach while the kids played nearby. And after everyone went to sleep, I’d pull out the laptop and work on various projects until past midnight. ☀️🏖️🌙💻

Among other things, I created a new post format for this Steamboat. I called it Liberty Workbench, and the concept is to let a single idea have more space to breathe.

So far, I’ve published two pieces. I can already feel how the format is shaping the content. I’m excited to do more, and they won’t all be philosophical like the first two. Some may be about a business, a technology, a film, a book, whatever I feel deserves a more thorough exploration.

Because I wasn’t thinking about the day-to-day, I had a chance to zoom out. I improved dozens of corners of the newsletter. Parts that I had not even thought about in years. The About page was dusty and full of cobwebs. I refreshed welcome emails, headers and footers. I created a Start Here page for new readers to discover favorites from the hundreds of Editions and thousands of pieces of writing in the archive.

Even if you’ve been around for a while, I bet you’ll find things you like on the Start Here page.

None of this happens without you, though. It’s not as fun if you’re alone, just a guy in pyjamas typing stuff on the computer up here in Canada. I appreciate you 💚🥃

So six years.

The next six would bring us to July 2032.

What will the world look like then? Who will I have become after 2,191 additional days of exploring, learning, thinking, and (hopefully) growing?

Who will you be?

🇨🇳 China’s Open-Model Calculus: Open Today, Leverage Tomorrow 🧨

Ben Thompson (💚 🥃 🎩) had a strong piece on Monday, doing a 360-degree overview of Chinese open weights models and their impact on U.S. AI labs and national security.

Here’s one highlight:

The strategy for China is obvious: commoditize your complements. Note that Xi explicitly ties openness to AI “moving from the digital world into the physical world”; the physical world is the world dominated by China, and the country’s lead in areas like robotics is going to massively benefit from widely available AI models.

Along the same lines, China does not want the U.S. to gain an asymmetric advantage in AI; to the extent that China can weaken the U.S. frontier labs while strengthening any and all potential U.S. adversaries so much the better, and it can benefit from the innovation that will attach itself to an open ecosystem.

All this got me thinking about China’s approach, and to better organize my thoughts, I decided to write them out. I’m focusing here on potential downsides. A vibrant global open model ecosystem has many benefits, but that’s for another day. Keep this in mind, no pitchforks.

Also, I’m not assuming a single master plan. Much of this can emerge from separate actors following local incentives. But decentralized incentives can still add up to a coherent strategy.

Priority zero for the CCP is that they don’t want to be dependent on American AI technology. The logical conclusion is they need to create their own AI.

Strategy on the Supply Side

Because they don’t have a competitive domestic source of compute, they need to build up their own semiconductor supply chain. This takes time and aligned incentives (both sticks 🪈 and carrots 🥕), and in the meantime they have to make up for their lesser access to compute.

To be clear: lesser doesn’t mean small. There’s a lot of compute available to Chinese labs, across a mix of Nvidia GPUs they bought before export controls took effect (and even after that, enforcement seriously lacks resources), GPUs smuggled into the country, GPUs hosted in the cloud elsewhere, and, increasingly, locally designed and made GPUs and ASICs.

American labs won’t be buying Huawei Ascends any time soon, so the scale has to come from Chinese labs being incentivized or pressured to move their models over.

Distillation & Benchmaxxing

That’s still not enough to match the big American labs who are training models on as many of the latest GPUs and TPUs as they can get plugged in. So a lot of the gap appears to be closed through distillation of the frontier models, acting as a relatively cheap ingredient that makes the recipe better. 👨‍🍳

There are all kinds of ways to infer how certain models are distilling others, and Anthropic says it identified industrial-scale extraction campaigns by DeepSeek, Moonshot, and MiniMax.

The above was made by Typebulb and is a clever one based on cross-entropy, using the stylistic fingerprints of each model to see which models sound like each other. You can see for yourself.

The two clusters I circled are Kimi K3 being most similar to Anthropic’s Fable 5, Opus 4.7, Opus 4.8, and Sonnet 5, and GLM 5.2 being most similar to Gemini (and also having a pretty strong similarity with Anthropic’s model too, though not as high as with Gemini).

I guess Claude was the favorite lately, because the stylistic distances from GPT are much higher ¯\_(ツ)_/¯

But Sol 5.6 just came out, so I wouldn’t be surprised to see stylistic similarity increase in future versions of open models.

The stylistic comparison between models doesn’t prove anything, but as one of many, many data points, it paints a pretty clear picture of a lot of distillation going on. I’m not saying it’s necessarily wrong. It’s a very rational strategy when it comes to sprinting up the trail as a fast-follower.

But it probably does make it harder to get past the frontier models that you're distilling and blaze the trail yourself, especially when combined with another thing that seems to be happening: Benchmaxxing.

A recurring pattern is that a lot of the Chinese models come out with amazing benchmarks, “Close to Fable 5!” Then users get to try them with real-world stuff for a few days or a few weeks, and the excitement dies down. They’re very competent, they’re very good, but in practice they are farther behind the frontier than just the benchmarks would lead you to believe. Or they are more expensive than the cost/million tokens make it seem because they are less token-efficient (this is one of the main criticisms of Kimi K3).

Benchmaxxing is also a rational strategy.

(To be clear, every model is optimized for benchmarks to various degrees, either on purpose or because some benchmark materials leak into training data. But some push it much further than others. The Llama 4 saga is a good example of that.)

If OpenAI and Anthropic are getting all of the attention, how do you convince users to switch and try your thing? There's friction there. You need activation energy. So you need to make a big splash and convince them that you're not offering a second-rate thing, but a first-rate thing at a really low price. And that's exactly the hype cycle with these models.

So that's the supply side.

Strategy on the Demand Side

The next part of the strategy is to release the models as open weights rather than try to compete with the big American labs with proprietary models.

Why?

"Commoditize your complements," of course. But what is the complement here?

China is behind at the model layer, but it dominates the physical layer those models plug into: robotics, manufacturing, hardware, and energy. The physical world is home turf. 🏭🏭🏭🏗️🦾

Driving the price of AI toward zero doesn’t just hurt the labs charging for it. It actively helps the layer where China is already winning.

That’s arguably the biggest reason. But there are two more that make open weights specifically attractive.

First, releasing strong models for free can hurt U.S. AI efforts. Any paid inference done on Kimi or GLM instead of Claude or GPT is diverting $ away from them, which they could reinvest in R&D and capex. 👨‍🔬

Not 1:1, because if you run Kimi on a U.S. hyperscaler, that money can still go in capex and stay in that ecosystem, but the dollar amounts are lower, and the labs are not getting it, so there are still fewer dollars going into U.S. AI progress.

The counterargument is that cheap models expand the market, creating workloads that otherwise wouldn’t exist and increasing demand for American clouds and Nvidia hardware. Both effects can be true. The question is which one dominates and which has the biggest effect on the rate of frontier progress.

Second, a widely adopted open model is a dormant asset in a conflict.

There are two ways to turn a model everyone uses into a weapon. The obvious way, and the smarter way. It looks like China is doing the latter.

The obvious one is to poison it: subtle vulnerabilities in the code it generates, backdoors, something that quietly phones data home (🏴‍☠️). The trouble is that going full black-hat is a one-time move. You eventually get caught and the models get banned, and you’ve spent all that hard-won adoption on a limited exploit, and probably not at the time of your choosing. So now you’ve got no access and no trust.

BUT

The patient version is scarier: just ship genuinely good models and don't do anything nefarious with them.

Sure, censor Tiananmen and Winnie the Pooh. Whatever. But nothing that would justify a ban. The models are free, they're good, they keep improving, and they work their way into many corners of the Western IT stack (in ways that are probably impossible for anyone to track).

Then, if a real conflict ever comes, you can decide to stop shipping. Freeze the weights, stop releasing updates, and let the pain ripple out through everything that depends on these models.

Sure, they can keep using the last version you shipped (can’t unring that bell 🔔). The weapon isn’t a kill switch. But it’s control over the upgrade path. At AI metabolic rates, any model version will age quickly, and whole industries built around these open models risk falling behind. In normal times, this may not matter too much, but I assume this card would be played in a conflict situation (🃏), where a few months could be decisive.

The second-order damage matters too. For years, those free, excellent models were soaking up the oxygen (aka token share/revenue) that might otherwise have gone to Mistral, Thinking Machines, Nvidia Nemotron, and the rest of the Western open ecosystem.

When you pull back, whatever's left to fall back on is weaker than it would've been if you'd never competed at all. That’s what ties reasons 1 and 2 together: flooding the zone with free models is what almost assures the fallback is weakened at the exact moment you'd want to pull the rug. And it cuts both ways: the same flood that weakens Western alternatives has been strengthening China's own ecosystem through usage data (on APIs), evals, better-tuned models for various hardware stacks, code contributions, etc.

Then again, this is partially self-correcting. The moment the threat gets legible, the West’s incentive to de-risk kicks in: the more credible the embargo looks as a weapon, the more reason the West has to build the fallback that defuses it.

Bringing It All Back Home (and I don’t mean the Dylan album)

So it looks like: growing AI independence, a maturing domestic chip industry with built-in demand, a cheap fast-follower pipeline, revenue drained away from rivals, cheap AI flooding the physical-world layer where China already leads, and a pressure point you can flip later. As a bonus, it makes you look great as the “open” one, the rebels fighting the “closed” empire.

I've described this as if there's a war room in Beijing directing the playbook. There probably isn't one, or at least, not one masterminding the full thing. A lot of this is just separate actors following local incentives: labs chasing benchmarks to get noticed, companies picking the cheapest good-enough model, the state wanting off American tech.

But the dots can connect whether or not anyone's coordinating them.

Steve Jobs Fired Two Board Members for Agreeing With Him 🍎🥾🚪

Friend of the show David Senra (📚🎙️) had a great conversation with Ed Catmull:

• 🎧📄 Ed Catmull talks with David Senra

I recommend the whole thing (and Creativity, Inc.), but one thing Catmull said stood out:

Ed Catmull: Pixar was a public company for 10 years, starting in ‘95, when we went public, until 10 years later, when we were acquired by Disney. In that 10-year period, Steve fired two members of the board of directors at Pixar.

The reason he fired them was that they never disagreed, and he said, “If they don’t disagree with me, then they aren’t bringing any value to the company.”

That’s an unusual way of thinking, and he really believed that. Our board meetings were lively; they were loud, and they were thrilling. And you know, we made great progress.

The rest of the people on the board had very strong opinions, did not agree, and Steve loved that. And I would say, a lot of executives probably say they want that, but Steve really meant it. He and I disagreed a lot. We didn’t argue. We disagreed, and we’d have week-long discussions about something.

And in the end, about a third of the time, I would realize he was right, and about a third of the time, he would realize I was right. But the other third of the time, I just did what I wanted, and he was fine with that because we had discussed it.

What’s the actual goal of doing this?

If you do it because you love the jousting and drama, you’ve copied the ritual but not the reason. Feynman would call it a cargo cult.

The disagreement isn’t the point. In fact, I can easily imagine some bosses mangling it and applying this anecdote mechanically, incentivizing reflexive contrarianism and making the collective thinking worse.

Disagreement is a means, not the end. It’s useful *only* when it surfaces something the room would otherwise miss.

Catmull explains the distinction:

Ed Catmull: The whole point is, how do you get to the insight? How do you surface things? Because it’s hard to get underneath things. I would say that a lot of people like to go down one layer. […] You can’t do that. You’ve got to keep peeling away the layers to figure out what’s really underneath it. […]

And getting at underlying factors is inherently a long-term strategy, and it’s a difficult one […], and you need different mechanisms within an organization in order to get to better insight. [...]

[T]he discussion is always about the topic. It isn’t about who’s right.

Sometimes going deeper is a pleasure. Sometimes it means uncovering one delight after another.

But sometimes going deeper is painful.

Sometimes it means admitting you were wrong. Maybe admitting you were wrong in public for a long time. Maybe it means admitting you’re not as smart as you thought you were, and you should be listening more to other people who are smarter than you.

Hope for delight, but be ready for humility.

👨‍💼📋 A Tale of Two Cities Workforces, AI Edition 📁🖇️

Noam Segal and Lenny Rachitsky surveyed about 6,000 people across product, engineering, design, research, marketing, and other tech roles to see how the vibes are out there (and how they compare to last year, this being the second year they run the survey).

They did a podcast where they discuss the results in depth:

• 🎧📄 How tech workers actually feel about AI in 2026 | Annual AI sentiment survey (Noam Segal)

My takeaway is there’s quite a severe bifurcation out there, and the vibes are very Yin Yang.

Some are having the time of their lives. They’re more creative, they can do things they couldn’t have before, and they can go out of their silos and touch more things (designers writing code, engineers doing design, etc). They are exploring, learning fast, and growing.

Others feel burnt out and anxious. Like any productivity gains just mean they’re expected to do even more, keep track of more things, ship more PRs per day, review more projects in parallel, work 24/7 because agents never take breaks.

The line that stood out to me from the podcast was “full gas on neutral.”

Noam Segal: One explanation, for example, is that at the top of the pyramid, VPs are benefiting more from AI because they’re getting all of this stream of information and knowledge being processed by AI, making their jobs a lot easier, whereas ICs are each scrambling to build all of these micro SaaS products within the companies they work for.

No one knows what anyone else is doing. There’s a lot of duplicative work. It’s a lot easier to build products these days, but a lot harder to maintain them. And so I think a lot of ICs are feeling like, there’s a saying, full gas on neutral.

You are pushing the pedal to the metal in your car, but you’re in neutral gear, you’re not going anywhere. I think that’s the feeling that a lot of ICs are having these days with these technologies. I keep building these things, but I’m not having the impact I want. Everyone else is building too.

There’s lots of confusion, and it’s just not worth it anymore.

This disconnect is dangerous.

Those having a ball should do more to connect with the other side, to understand and empathize better. Not only because it’s the right thing to do on a human level, but also because all this resentment and negative energy will probably be harnessed by those who will promise to fix it all, and these politicians may not do it in a smart way and end up doing more damage than good.

Personally, my life is incredibly richer thanks to these tools. I do dozens and dozens of queries per day about various projects or questions that pop into my head, or things I don't understand, or problems around the house that I can find fixes for. I learn faster than ever before.

I even find I'm a better parent to my kids because I can explain more things to them than just what I already know. I can find intuitive explanations about all kinds of things that I may not take the time to Google and research and synthesize otherwise.

So I probably fall more on the excited side of it.

But, as it always is, life is more nuanced and complex than that. It doesn’t mean I don’t have worries. It doesn’t mean I don’t feel the uncertainty. It doesn’t mean I don’t wonder what my kids will do to earn a living when they’re grown up. And it doesn’t feel great to not have answers and to just hope for the best.

Part of it is the illusion of certainty. The past was also very uncertain, but looking back makes it seem like it was on rails and everything was simple and obvious all along. Still, it’s probably true that during fast-moving technological transitions, uncertainty ratchets up even higher than normal.

The way I look at it is a bit like this Venn diagram that my wife has in her office:

All of the potentially bad things about AI, all of these uncertainties, I can't really do anything about personally. I can observe the field, but I don't have impact.

But all of the good aspects of this, I can harness in my life. I can use these tools to explore, to teach myself, to help my kids.

My oldest boy has been vibe coding a 16-bit Nintendo-style video game. I've advised him a little bit, but he's mostly been doing it by himself. When he doesn't know how to do something, he can ask the AI to explain it, and then we discuss what he learned together, and I give him some advice. But I let him execute it, I don’t want to do it for him. It's like having both a tutor and an engineering team on call… as a 12yo!

He's having a blast, and I'm very proud of him. I'll write more about the specifics of that project at some point in the future.

But that's just to say that if I decided not to use AI just because of the negative aspects, I would be missing out on some of the great aspects, punishing myself, yet not really having an impact on how things unfold at the macro level.

📽️ IMAX 70mm is a Lost Art?! 🎞️

I haven't seen The Odyssey yet, but I keep hearing about the experience of seeing it in IMAX (my friend Ed was just telling me he’s going for a second time). And I fell down this rabbit hole about how the very best version of IMAX is a lost art that we don't really know how to build anymore. 🤯

Here’s a video of one 70mm copy of the film being delivered. It weighs over 600 pounds!

(The shipment in this video is claimed to be 846 lbs, although projectionists describe the film print itself as weighing about 600 lbs. I’m guessing the difference is the platter, crates, or other shipping hardware, but I couldn’t find a precise breakdown.)

A recent Variety piece explains what’s going on:

Only 25 theaters in the U.S. are equipped to project “The Odyssey” in true Imax 70mm film, prompting moviegoers to embark on cross-country road trips (and even delaying pregnancies) to experience the cinematic milestone. [...]

“We’re sold out in some theaters into the fifth week already,” Gelfond told Variety. “There’s certainly more demand. The problem is they haven’t made new Imax film projectors in about 50 years. So we retrofit them, rebuild them and part of our strategy is to see how far we can take it. But certainly, demand-driven, I’d like to see more.”

50 years?!?

I didn’t realize IMAX went back that far. I had to look it up: The company was founded in 1967, and its first projection system debuted in 1970.

Sources at Imax confirmed to Variety that many of the parts needed to build these specialized film projectors “simply no longer exist.” The original design files were created roughly half a century ago, but as Gelfond alludes to, they were never properly maintained. As a result, Imax no longer has a complete manufacturing blueprint — and much like the lost tribal knowledge of the Apollo-era spacecraft, very few engineers working today fully understand the systems.

The loss of institutional knowledge can also be traced to Hollywood’s transition from film to digital projection that began in the late 2000s. As theaters began converting to digital projectors, which are cheaper and easier to maintain, manufacturers stopped producing film projectors and the replacement parts that go with them. Only in recent years, thanks to auteurs like Nolan and Denis Villeneuve, has interest in the format begun to rebound, even if the format remains a niche experience

Theaters can’t beat the living room on convenience, so leaning into spectacular formats like IMAX 70mm that people can’t reproduce at home seems like a no-brainer. They help make films into special events.

Getting just 11 more projectors running for The Odyssey was itself an, er… odyssey:

After reaching a near-record year at the box office in 2023, fueled by Nolan’s “Oppenheimer,” Imax knew it needed to expand its fleet of 70mm film projectors ahead of “The Odyssey.” For over a year, Imax embarked on a massive effort to track down broken, abandoned and often-forgotten projectors, salvaging parts to refurbish and install additional projectors. The strenuous process also required training 60 new projectionists from scratch. [...]

The effort ultimately resulted in 41 Imax 70mm locations worldwide for “The Odyssey,” up from 30 for “Oppenheimer.”

IMAX let the industrial knowledge behind these projectors disappear. Now, to meet renewed demand, it has to excavate it.

That’s technological archaeology.

🗣️💬🌏🔍🤖 We need auto-translation everywhere, stat!

I agree with friend-of-the-show Rohit (💚 🥃).

Machine translation has existed for years. The product breakthrough is making it good and cheap enough to disappear into a default background process that doesn’t require an explicit action.

As I’ve said many, many times, friction matters more than people think. If you have to click even once to read that Japanese message, most people won’t do it. They may do it once in a while, but they won’t hang out on Japanese Twitter or forums.

Not only that, but the friction runs both ways. It’s a two-sided chicken-and-egg problem. 🐓🥚

Even if *you’ve* always been willing to translate other people’s posts, that doesn’t help much if they aren’t doing the same. They may never discover your stuff, reply to it, or make themselves known to you.

Auto-translation changes both sides of the network: It helps you discover them, and them discover you. ↔

I hope auto-translation diffuses rapidly to all corners of the Internet (Reddit, comments on Instagram, whatever) and helps tear down language barriers around the world.

What is Google Doing⁉, Part 2 🤨

Follow-up to:

• What is Google Doing? 🤔 (Edition #644)

• 🧠 Is Google Experiencing a Brain Drain? 🔋🪫 (Edition #645)

The Goog just released a bunch of new models, with Gemini 3.6 Flash being the flagship of that crop. On paper, it seems like a pretty decent upgrade over 3.5 Flash, particularly when it comes to token efficiency. On top of that, they’ve also cut output price from $9/million tokens to $7.50/million tokens.

Sounds pretty good, right?

Except that whenever I try Gemini, I catch it making all kinds of errors that ChatGPT and Claude rarely make anymore.

On the VERY FIRST THING I asked Flash 3.6, it made the dumbest error that it should have caught and corrected while reasoning and before writing its user-visible output.

Here’s a play tragedy comedy in three acts:

I asked it to give me the benchmarks of 3.5 Flash vs 3.6 Flash. Simple enough, right?

It gives me 3 Flash vs 3.5 Flash.

I asked it why it gave me Gemini 3 Flash when I specifically asked it about 3.6?

It says my mistake, but then it doesn’t describe the actual mistake it made. It doesn’t mention 3.0, just 3.5. So I have to tell it again, and it finally admits the error. 🙄

This kind of stuff feels very 2024 to me, not 2026.

The other bad news is that Gemini 3.5 Pro is still nowhere to be found, so 3.6 Flash is now better on benchmarks than 3.1 Pro. That’s embarrassing.

It’s also sad how slowly their harnesses improve. The Gemini website hasn’t improved much in ages (at least not in ways I can detect). I’ve given up on even trying the desktop Mac app for now because it was so bad, and I never hear coders talk about using Antigravity.

Google said:

Beyond today’s releases, Gemini 3.5 Pro is currently testing with partners and we plan to make it broadly available as soon as it’s ready. In parallel, our team is already focusing on building the next generation of models. We have started our most ambitious pre-training run yet, for Gemini 4, and are excited by the progress.

Ok, but promises promises… At this point, you need to deliver deliver.

What matters is whether the models that Google releases help them catch up to the frontier, or if the Giant with more money, compute, and AI talent than anyone just can’t transmit all that power from the engine to the wheels anymore.

Where are you, Demis?

🎖️ 1917: You Only Know What They Know + My War Films Project

This is an expanded version of a piece originally published on OSV Field Notes. If you aren’t already a subscriber, I think you would love it. Check it out.

I’ve started watching war films with my 12-year-old. Not Rambo III or Commando. The more historically grounded ones. It started when I mentioned that something happened “during World War II” and realized the words meant almost nothing to him. How could they? My own love of history began with films rather than textbooks. They aren’t always accurate, but they gave those words meaning. Now I’m trying to do the same for my son.

So I built us a little curriculum: 1917, Saving Private Ryan, and Band of Brothers. They’re more violent than what I usually watch with him, but I know my kid, and the violence isn’t gratuitous. It’s supposed to be horrible.

We started with 1917 because I wanted to begin with the First World War before moving to the Second. I’d already seen it twice, including in the theater, and Roger Deakins is my favorite cinematographer.

Everyone talks about how it’s made to look like a single continuous shot, unfolding in near real time. It’s neat, but it’s not what I care about. What makes it special is that the camera never leaves the soldiers. You see nothing they don’t see, you know nothing they don’t know. There are no establishing aerial shots of the battlefield, no cutaways to the Germans setting their trap, no shot of Blake’s brother waiting at the other end. That absence denies us the reassurance of knowing more than they do.

In 1917, you’re just there. It’s the closest a film has gotten me to what it might feel like to be a young soldier having to cross no man’s land. I pointed out to my son how many of the soldiers looked like teenagers, or barely out of their teens.

The violence happens the way it often does in life: fast, brutal, unannounced, no slow motion.

The filmmaking is incredible. Sequences that would be the highlight of another director’s entire career are just stacked one after another. The ruined town at night, lit by drifting flares and fire, is out of this world.

Being told about a war and seeing one are very different. The next time I tell my son something happened in 1917, he won’t hear only a date.

🪖 The Project Continues: Band of Brothers & More

I wasn’t sure where to go next. Saving Private Ryan was my first idea, then I thought maybe Dunkirk. I ended up going for the amazing Band of Brothers because it follows these men across a longer period, from boot camp to the end of the war, and I think the D-Day scenes in Saving Private Ryan will be even more effective *after* this.

So far we’ve seen three episodes, and my son loves it. We have tons of discussions during (we pause it) and after the episodes. The captured German soldier who grew up in Oregon sparked a good discussion.

I had forgotten how intense parts of the Carentan episode are, but confronting how bad things can get is part of the point. And we haven’t even got to Bastogne yet.

This whole show is such an incredible achievement. I was due for a rewatch anyway, but I’m glad I get to share it with my boy. In a few years, I’ll do the same with my younger son.

Liberty Workbench is an occasional series where I put one idea on the bench and think it through with you.

I first published a version of this essay in 2018 and remastered it in 2021. But this is a different beast: entirely rebuilt and greatly expanded with ideas I’ve had in the years since.

I’ve noticed a recurring pattern in my fields of interest, and I think it happens elsewhere too.

It usually goes like this:

People who have been around the field for a while become increasingly disenchanted with their old mentors. They used to have good insights, but now mostly recycle the same things. Their best stuff was their earlier stuff. And so on.

It often leads to a kind of retroactive downgrade in the mentor’s perceived value.

I’ve seen it a lot with Warren Buffett over the years. People complain that his letters and interviews have become boring and redundant.

Part of what’s going on is the ‘curse of knowledge.’ Once you know something, it’s hard to put yourself back in the shoes of someone who doesn’t. Compound interest, anchoring bias, and non-zero-sum thinking might seem so-basic-you-don’t-even-have-to-think-about-them now. But a younger version of you had no idea what any of them meant, and learning and integrating those ideas likely changed how you saw the world, at least a little.

Some people happen to be really talented at doing certain things and really good at teaching others about them (those two circles in the Venn diagram don’t always overlap).

People like Warren Buffett, Mark Leonard, Richard P. Feynman1, Charlie Munger, Andy Grove, Ed Catmull, and Martin Scorsese.2

These are pretty revered names, but many other mentors and teachers aren’t superstars. They may not be as well-known, but they’re far enough ahead of you in something you want to learn.

🪣🚰 The archive and the drip

When you first discover a mentor, you don’t encounter their ideas at the rate they produced them. You can consume years or even decades of accumulated work in a matter of weeks or months. Speed-running through someone else’s hard-won wisdom.

You’re also not consuming a random sample of everything they’ve ever produced. Usually, you start with the greatest hits: the best book, the famous talks, the most quoted ideas, the highlight reel. 🏆⭐📚

Once you’re caught up, that ‘best of’ filter is gone. Now you get each new letter, interview, or idea in real time, at the rate one person can produce it. You drained the reservoir.

It’s an unfair race.

Nobody can keep coming up with brilliant original ideas faster than someone else can learn them. You can consume decades of a mentor’s accumulated work much faster than they can give you another decade of it. 📜

The way you consume the work changes too.

Early on, you seek out the books and talks, take notes, and actively try to integrate what you’re learning (📄🔍). Years later, a new letter may get a skim because you see where it’s going.

Now imagine that same letter is the first thing a smart reader ever encounters from Buffett. The anecdotes that feel stale to you might be revelations to them. Same letter, different reader.

Familiarity ≠ mastery

The other half of the story is you: you can become familiar with a mentor’s ideas much faster than your actual abilities grow.

The green line is the mentor. They’re already at or near the top of their field by the time you discover them. If they weren’t, they probably wouldn’t be on your radar.

You start near the bottom, in the steepest part of your own learning curve. There’s plenty of low-hanging fruit, so your understanding and ability can improve quickly. Eventually, that curve begins to level off. You may keep improving for the rest of your life, but the easy gains are behind you.

You can learn the vocabulary, recognize the patterns, and anticipate what they’ll say. You may know Buffett’s sayings well enough to quote him at the drop of a hat. But knowing the sayings is the easy part. The hard part is developing the judgment that produced the sayings and the ability to execute that produced the results.

🗜️ The part that doesn’t compress

This is the distinction that gets overlooked. The mentor may not have become much less impressive in absolute terms. Their marginal value to you has declined because you’ve already absorbed so much of what they have to teach.

Some parts of a skill compress well. Principles can be written down, examples can be studied, and vocabulary can be learned relatively quickly.

Other parts don’t. Judgment and execution depend heavily on tacit knowledge: things an expert knows how to do but may struggle to fully explain. Temperament and consistency aren’t knowledge in the same way. You can know exactly what to do and fail to do it. All four are much harder to package and transfer and tend to be built slowly through experience rather than absorbed from a book, talk, or letter.

There’s no clean dividing line or magic crossover point between the two. Those qualities may be present throughout the entire journey. But once the foundations are widely understood, plenty of people know the same concepts and repeat the same principles. What often separates exceptional performers from the rest is the part that doesn’t compress.

That means you can close much of the visible gap between yourself and a mentor without closing the part that matters most. Your familiarity goes up fast, but your independent ability improves more slowly. A relatively small remaining gap can still lead to a LARGE difference in results, even if fewer and fewer of their ideas make you think “Oh, I never thought of that.” Both can be true.

This is why you get “mentor fatigue.”

Learning from them paid enormous returns early on because almost every lesson was new to you. Now the returns are harder to come by. The mentor may not have deteriorated. You’ve simply collected most of the easy gains.

To be clear, sometimes mentors do get worse and start phoning it in. Some even turn into grifters who coast on past glories. All I’m saying is that even when mentors keep it real, it’s common to see this effect.

What actually changed?

When an old mentor starts seeming less impressive, three things may have changed: the mentor, you, or the world.

Sometimes you really *do* outgrow a mentor. You begin to see their blind spots, notice where their rules stop working, and think past what they taught you. That’s different from simply knowing their material by heart.

When a mentor succeeds at spreading an idea, they can make themselves seem less original in retrospect. 🔄

It’s kind of like watching Blade Runner or Alien today. Their influence is everywhere. Others have built on many of their ideas, and many of their choices have gone from seeming original to conventional. So you may think, that’s it? Everyone does this.

But conventions start somewhere. Sometimes everyone knows the stuff because the mentor helped teach it to everyone.

There can also be a little status game hiding in all this. Admiring a canonical mentor is ‘too obvious’ and doesn’t earn Sophistication Points™. Dismissing them and replacing them with someone obscure is a way to signal that you’ve graduated. Attacking the top dog can be a way to try to raise your social status.

I think of the full progression as the ‘Snob Sandwich’:

First, you admire the mentor. Then you think you’re sophisticated enough to dismiss them. Eventually, if you keep progressing, you may become sophisticated enough to admire them again.

The admiration on the other side is different from the kind you begin with.

Early on, you admire the mentor because their ideas are new to you. Shiny! Later, you may admire them because experience (aka failing a lot and seeing how hard it all is) has shown you just how hard the simple stuff is.

It’s one thing to know that temperament matters, but it’s another to keep ice in your veins when the headlines are apocalyptic and everyone around you thinks you’re an idiot.

🔬 From novelty to depth

At some point, the game changes. Early on, learning is mostly about collecting new ideas. Later, it’s about paring your collection down to the essential ideas and going deeper into them. Where does this principle break? What does it look like under pressure? What happens when two good rules point in opposite directions?

You also have to do more of the work.

You can’t just sit there waiting for the mentor to blow your mind every time they open their mouth. You have to bring something to the table: better questions, real problems you’re trying to solve. The same paragraph you read 10 years ago may have something different to teach you after you’ve tried and failed a few times. Expertise grows as you apply old ideas in new contexts.

This happens with favorite albums too. You can know every note, then return years later and somehow hear more in it because you have more life to bring to it. The album hasn’t changed, but you have. Mentors can be like that too.

You need your own wisdom to combine with theirs to create a new hybrid strand. 🧬

Conclusions are easy to memorize. The process that produced them is harder to see, but that’s where more of the remaining value lives. How did they get there? What did they get wrong? What changed their mind?

Eventually, you have to go beyond your mentors. Read the primary sources they studied. Explore adjacent fields to learn completely new things. Try things. Some of what you find will transfer back in ways that aren’t predictable.

The closer you get to the frontier, the less likely the next useful insight is waiting for you in a neatly packaged quote.

They may seem less impressive to you now. But those ideas didn’t come pre-installed. By the time a mentor starts sounding obvious, it can be easy to forget who helped make them obvious to you.

Liberty Workbench is an occasional series where I put one idea on the bench and think it through with you.

I was listening to an interview with Adam Mosseri (head of Instagram since 2018), and he said this 👆

I've believed this for a long time. But there are levels to it, and I think we're jumping to a new one.

Rewinding a bit: taste was always important. What kept changing is how far you could take it.

(By taste, I mean the ability to notice meaningful differences, choose among plausible alternatives, and know what to reject. Agency matters too, but it does a different job: taste turns the wheel, agency presses the pedal.)

🧭 Direction

A lot of people have technical ability and creativity, but what usually distinguishes great artists is the filter sitting on top. The captain at the helm saying 'that way' or 'nope, not that way.'

If you have a powerful engine but you’re driving in the wrong direction…

In fact, sometimes great taste can compensate for limited ability in other areas. People made some great things with basic musical skills or simple prose. Good doesn’t have to be complex, even if it sometimes is.

Before industrialization, extraordinary taste could produce magnificent things, but its reach was limited. If you were lucky, you became some great lord’s “guy”. Like, yes, I have a guy who does my paintings. I have a guy to design my cathedral. ⛪︎

🏭 🌐 Leverage

Industrialization changed that. Judgment could now be embedded in a repeatable system, reproduced at scale.

The Porsche family (Ferdinand, Ferry, and Butzi) created a system that translated aesthetic and engineering judgment into beautiful cars made by the thousands, generation after generation. Steve Jobs’ taste had huge leverage because it rode the giant secular wave of personal computing, which went from almost nothing to almost everyone on Earth carrying a computer in their pocket (what computer is more personal than the smartphone?).

The internet added another layer of leverage on top of that industrial leverage: global reach and (near) zero marginal cost (👋 Ben).

The right product could now be put in front of the whole planet, and if it was found truly superior, it could pull far ahead of the competition. That’s the Google era. We forget it now because the company has ‘matured’ a lot since, but for a long time, early Google had both superior technology AND superior taste. Go on the Wayback Machine and look at the homepages of other popular search engines at the time.

Internet age = Power-law outcomes became more extreme

But scale amplified a different problem: organizational dilution.

Ambitious, complex products required large teams, long timelines, endless meetings, and repeated handoffs of tiny shards from one person to the next, with almost nobody owning the whole. At every stage, someone else had to interpret, approve, finance, or implement the original idea. By the time the product came out, it was more ‘design by committee’ than ‘singular vision’.

Part of Steve Jobs’ extraordinary ability was organizational. He had such a forceful personality that he effectively fought these tendencies, designing a system to protect a coherent vision: small teams, focus on a few products, directly responsible individuals, his Eye-of-Sauron 👁️ attention to every detail. The vast majority of other places don’t have that. How many things have you bought that were so aggressively mediocre that you wondered if the people who made them ever used them, even once? That’s the disconnect, the gap between someone with taste and the final product.

🧠💻 Thinking Sand Era

AI is a different kind of leverage than the ones before. Industrialization and the internet were both largely about reach. AI has the potential to work on a different axis. It may not provide much more reach than the internet, but it can increase fidelity by narrowing that gap.

Earlier forms of leverage made taste louder. AI may make it less lossy: more PNG than JPEG. If it becomes much easier to prototype, build, and iterate, the person with the vision and the filter can remain more directly connected with the final outcome. Less dilution, less derailing. Not necessarily louder, but ideally truer.

We went from:

A world of gatekeepers and 'idea translators' (publishers, large technical teams, manufacturers) → much more direct access.

We’re reducing the number of people a creator must persuade before an idea can become real. Fewer people need to interpret, approve, finance, or implement.

But there’s a different trap that must be avoided: if you escape design by committee but then fall into ‘design by model consensus’, it’s out of the frying pan and into the fire 🍳🔥 (is that how that idiom goes?).

Models are trained on the preferences and outputs of millions of people, and now everyone is using the same few models in similar ways. That combination can act as a different kind of virtual committee, one that sands off the edges and removes the spikes if it isn't robustly steered by someone with strong opinions and the willingness to stand behind them.

Have you noticed how every startup’s website looks the same lately? It used to take effort to copy Linear.

AI can also improve your judgment and taste, if used well. But knowing how to steer it well, what feedback to trust, and what to ignore is itself a form of taste. There’s a bit of a bootstrapping loop there.

🦄 Differentiation

Making was scarce → distribution was scarce → now judgment is scarce.

That's the pattern that keeps repeating in every era: some part of making things gets commoditized, and the value migrates to whatever's still hard.

As execution gets cheaper/easier, polish stops signaling exceptional judgment. You can ask AI to do something aggressively mediocre and uninteresting, and it’ll execute it beautifully.

Taste is escape velocity from Planet Average.

A paradox:

How quickly did the standard Midjourney image go from 🤯 to 🥱?

When everyone is good, the difference between the winner and the rest of the pack may be very small in absolute terms (look at the Olympics 🥇).

But a few percent of performance doesn't pay a few percent more. The gold medalist beats fourth place by a hair and walks away with the medal, the anthem, the YouTube homepage highlight clips, and the endorsements. Power-law outcomes, like we said about the internet era.

So if taste has the potential to matter more, what can you do about it?

🧑‍🎨 How can you train your taste? 🎯

Here’s the ‘obvious’ part that very few people actually put into practice.

If you listen to those who have great taste, many will tell you that part of it is innate, but a big part of it is trained.

The model-consensus trap, Planet Average where all the edges are sanded off…?

Training your taste is the defense. If the danger is getting pulled toward the middle, the whole game is stocking up on reference points that pull you off-center and make you spikier (to be clear, there’s great stuff in the middle too, but you can’t look *only* there). You want to deliberately feed on what isn’t averaged: the specific, the old, the weird, the deeply personal, the out-of-left-field stuff. Everything below is a way to do that.

📥 Improve your inputs

The best way I know to train your taste is to consciously consume a lot of great work. I’m always impressed when a favorite filmmaker, musician, or writer nerds out about their craft in an interview, and reveals how much they’ve seen, heard, and read across many genres and eras.

Great films, great books, great paintings, great music. Passive exposure isn’t enough. It's like what they say about deliberate practice: you get a lot more out of it if you do it with intent and intensity. Ask why why why why.

I see it all the time, the Exploration vs Exploitation imbalance. You can’t learn new patterns, find new reference points to calibrate against, or recharge your creative batteries if you never explore new things or have new experiences.

🔎 Deepen your attention

Don’t just casually watch your favorite films. Pay close attention, listen to interviews with the director, buy the making-of book that has the backstory on how it was created, the pre-production design work and concept art.

Another way is to find someone who really knows something and really appreciates it, and listen to them talk about it. It’s a way to see/hear through someone else’s eyes/ears. It can help you learn those skills of appreciation and analysis.

(Here’s Elizabeth Zharoff, a professional, classically trained singer hearing Stairway to Heaven for the first time. Watch what she notices.)

Why does this matter if you’re not making films or writing books? Because I strongly believe that taste, pattern matching, whatever you want to call these creative skills… They’re transferable to almost anything you do in life. From raising your kids to designing an experiment to giving a presentation to the C-suite.

🏋️ Exercise your judgment

A powerful way to exercise it is to make things yourself, do lots of iterations, and get lots of feedback. Generate alternatives. Predict what will work and see what happens, calibrate against the cold harsh reality that it’s really hard to make good things.

This is powerful feedstock for the pattern machine 🧠

If taste is pattern matching, then you have to train your brain on the right patterns. And you can’t stop at appreciation, you have to turn what you learn into understanding and decisions.

Roughly:

Try to increase all four factors.

Or the less mathy version:

Better inputs → closer attention → explicit choices → real feedback → updated taste ↺

That last bit is important. Taste develops recursively. It’s not static.

How can you expect to know what’s good or interesting if you rarely encounter really good or interesting things? (I’m trying to resist the impulse to make an analogy to doing pre-training and post-training/RL on an LLM 😅)

🧩 Putting it all together

AI makes taste more consequential than it already was in two ways: it gives individual judgment greater leverage, while making competent execution less distinctive.

AI can increasingly help you make almost anything. It can even help you judge the options. But at some point, you still have to make the call: Is this good? Is it interesting? Is it even worth making? That’s your job. And it may become the part that matters most.

The thing I'm least sure of: taste only captures value in a market that can perceive it. In feed-mediated markets (Insta, TikTok, YouTube), people still do the perceiving, but an algorithm decides what gets the chance to be perceived.

Optimized slop may win the mass game while taste matters most where people deliberately choose what to seek out: subscriptions (*cough* this Substack *cough*), word of mouth, or premium products. Though even if taste only drives a minority of the volume, it can impact a large fraction of the total profits (see: 🍎). Maybe slop wins attention while taste wins profits and cultural impact 🤔. I think that dynamic will hold, but if we notice that the most-rewarded work keeps getting blander and keeps working, maybe I’m wrong.

Invert it: All this new power WITHOUT taste just means you can create a lot more mediocre crap and add to the slopocalypse.

Liberty Workbench is where I put one idea on the bench and think it through. Every Workbench edition is collected here.

📋 What I want to remember

• Taste directs skill. It is the captain, not the engine.

• Technology gave taste leverage. Industrialization made the results of judgment reproducible, and the internet gave it global low-friction reach. But that scale meant large organizations diluted the vision along the way.

• AI is a new kind of leverage. Earlier jumps made taste louder (reach) but AI can make it truer (fidelity). Less is lost between vision and result (more PNG than JPEG).

• The catch: AI can also create a new kind of committee effect by pulling toward the consensus average, where everyone prompting the same models the same way ends up. Fidelity only pays off if someone with good judgment and strong opinions is steering.

• When polished execution becomes abundant, judgment becomes the bottleneck. The ability to choose, reject, and refine is what differentiates the result.

• Taste can be trained: quality of inputs × depth of attention × frequency of judgment × quality of feedback.

• Taste may win the profits even if slop wins the attention — but if the blandest work keeps winning and keeps working, that bet is wrong.

🎶🎼😃 Here are two concrete tricks for getting unstuck musically, wrapped in a love letter to music. 💌

If you’ve been on this steamboat for any amount of time, you know I love music.

It’s one of the best things in life!

It’s a powerful drug without the downsides. It can change your brain state, perception of time, your mood, it can transport you back in time, take you on all kinds of journeys.

And it’s also a social network (in the same way that sports are a social network — but I just never signed up for an account there 😅).

You meet a music fan who loves the music you love and you have something to talk about and share. I’ve really enjoyed seeing both my boys get more and more into music, and I love listening to songs with them (and I’m surprised by how they independently discover older music and like it just as much as I did when I was their age).

Sometimes all it takes is sitting back with headphones and truly paying attention to discover a whole new layer to a song you’ve heard 100 times.

There are two things I’ve been experimenting with lately with music that I want to tell you about.

• Trick 1: Ask AI what to listen for 📋👂

The first is asking an AI for what you should pay attention to and context on a song or album. I think I got this idea from Tyler Cowen, who asked ChatGPT about a Sibelius symphony or something like that.

As I wrote last week, I’ve been getting back into Led Zeppelin lately, so I tried it on the first two albums and this is what I got. Here’s an excerpt:

It then went song-by-song over the two albums with a paragraph on each.

After my original try, I built a better prompt for you to play with (but don’t hesitate to customize it to your taste!):

I'm about to listen to **[album/song]** by **[artist]**.

Please make me a listening guide for me to read before/during listening. Do a web search first so you can use accurate context, release details, critical reception, artist quotes/interviews if available, and anything interesting that may not be in your general knowledge. Use the standard album edition unless I specify otherwise. Don’t use flowery prose, keep it conversational, clear, and to the point, like a music-loving nerd friend telling you about it. (If this is a single song rather than an album, skip section 3 and instead expand section 2 into a close listening of the track. If it’s just an artist, turn section 3 into an album-by-album guide, giving a quick overview of albums and which are considered to be the best and why)

Structure it like this:
1. **High-level context**: Give me the essential background on the artist, where this album/song fits in their career, when it came out, what was going on around its creation, and why people care about it. Keep this concise but rich. 2-3 paragraphs. 
2. **What to listen for**: Give me 5-8 general things to listen for, depending on how much is genuinely interesting. These can include themes, lyrics, production, rhythm, arrangement, vocal performance, instrumentation, influences, genre context, sequencing, cultural impact, or easy-to-miss details. Prioritize things that will actually change how I hear the music. Also keep this concise but rich.
3. **Track-by-track guide**: For each song, give me a short paragraph that:
    - Describes the song's mood, sound, and role on the album.
    - Points out one or two specific things to notice while listening.
    - Explains how to best appreciate it, especially if it is subtle, strange, repetitive, long, or easy to underestimate.
Please avoid generic praise. Be specific, concrete, and musically useful. Mention disagreements or mixed reception where relevant, but don’t hedge everything, I don’t need a Wikipedia page, just a concise tour guide. Cite sources for key factual claims, but don't let citations overwhelm the guide. Help me appreciate the music better while I'm listening.

I've tried it with all kinds of stuff, from Leonard Cohen to Metallica to John Coltrane, and so far I really like what it gives me.

This kind of context really changes the listening experience. It’s a bit like having a fan of the band introduce you to them and give you pointers on what to listen for.

• Trick 2: Feed it your playlists and ask what's missing ☑︎☑︎☑︎

The second thing I’ve been doing is to export some of my playlists from Apple Music (but the same works in Spotify), upload them, and ask what it thinks and what I could add.

I first tried with a playlist that I shuffle while I read and write. It’s all instrumental music, stuff like Mammal Hands, GoGo Penguin, Tingvall Trio, Emil Brandqvist Trio, Portico Quartet…

I thought I had explored that sonic space pretty well, but it suggested about a dozen artists to check out, and I ended up adding about half of them to this playlist (or other playlists, if I liked them but they weren’t quite the right fit).

That’s a very high hit rate!

But this is what AI is good at: Pattern matching. If you give it a playlist with 87 hours of music (as I did), it has an *extremely* specific pattern to work from.

I’ll be doing the same with some of my other playlists.

This isn’t as fun as having music nerd friends to get recommendations from and listen to music with, but since there’s too little of that in my life anyway, this is the next best thing (and wouldn’t replace that anyway, it’d just give me more things to talk about with music nerds).

If you feel like you've been stuck musically, or going around in circles like many people do after their teens and early 20s, give this a try. It may help you discover new things or rediscover old faves.

Do you listen to instrumental music while working? What are your faves? What artists am I missing? Reply or leave a comment and tell me.

🤖🤖🦅🇺🇸 De Facto Nationalization by Vibes: A Terrible Way to Regulate the AI Labs 🗽⛓️

Both Anthropic and OpenAI have new frontier models that are being blocked from public release by the U.S. government right now.

There doesn’t appear to be a real process, just whatever top officials or the president feel like at the moment (just like the supply-chain risk designation is just a vibe, it seems, and nobody quite knows what it means anymore).

Is ‘nationalization’ too strong? At this stage, probably. But functional control matters. The power to decide what a company can ship, when, and to whom is arguably the most important lever of all. Ownership without a say over output is no longer full ownership.

And if this is happening with these models, why wouldn’t it happen to the next ones, which will be more powerful and thus potentially more dangerous? Unless something changes, that is. Do we need a breakthrough in guardrail technology? A step up in mechanistic interpretability, classifiers, and general model security..? 🔐🔍

But if the gating isn’t based on security facts, what exactly would better interpretability and classifiers unblock? 🤔 (It’s like the old saying: You cannot reason a person out of a position they did not reason themselves into.)

That’s not to say that there can never be any reasons for blocking the release of models, but the lack of clarity and transparency seems worse than the kind of regulation that was feared not long ago.

Good regulation should at least try to be fair, legible, and predictable, so businesses can make plans and comply with the rules. Whatever this is, it doesn’t look like that.

In fact, because Mythos was only available to ‘defenders’ to harden software, blocking it (and Fable, the heavily locked-down version of Mythos that was briefly public) probably weakens the state of readiness for cyber attacks and cyber crime. Same with the new GPT-5.6 (more on that below), which is apparently in the same ballpark when it comes to finding (and fixing) security holes in software.

I’d certainly feel better if the engineers who maintain mission-critical code weren’t wasting a single day and still had access to the best models rather than being downgraded for an unknown period of time.

There’s also a slightly absurd recursive version of this: Anthropic itself got downgraded. The order reportedly applied to “any foreign national,” including Anthropic’s own foreign-national employees, and the company said it couldn’t reliably enforce that person-by-person, so it initially shut off Fable 5 and Mythos 5 for everyone. The company whose CFO says Claude Code writes 90%+ of its code spent weeks with its own internal AI stack kneecapped (reverted to Opus?) by a Friday-evening government letter (with 90 minutes to comply 😬).

Maybe if the attackers (🏴‍☠️) were all only using Anthropic and OpenAI models, restricting access would be a net positive because of the inherent asymmetry between attack and defense (you only need to get in once vs you need to stop all attacks), but because Chinese models keep improving rapidly in the meantime (eg. GLM-5.2), any lost time for defenders matters.

It reminds me a bit of the encryption wars in the 1990s, when the government tried to ban strong encryption from being “exported” outside the US (limiting it to weak 40-bit symmetric encryption and 512-bit RSA). In practice, strong encryption was available anyway, but the population of weak targets for black hats became much bigger.

Let’s do a thought experiment. 🤔💭

What if, a few years ago, the government had told Amazon that they couldn’t release a certain AWS feature because so much of the web’s critical infrastructure was hosted on AWS and there were large systemic risks from it? What if you screw it up and hospitals, banks, the power grid goes offline? What if outages or security flaws end up costing the economy billions of dollars in damages and downtime?

What if the government had told Meta that they couldn’t do XYZ on its apps because too much of the country’s communications was going through Facebook/WhatsApp/Insta and mistakes or successful attacks on the system could give adversaries access to personal, potentially sensitive information on hundreds of millions of people, millions of businesses, and cause disruptions to all kinds of things?

What about Google? How much of society relies on Google Search, Google Maps, Gmail, YouTube..? That’s a big risk if things go wrong! etc.

All these arguments are not crazy on their face.

Maybe it’s because the “old” Big Tech accumulated power slower than the AI Labs, so a bit like what they say about going bald (👴), we didn’t notice it that much from day to day until it was pretty far along. With OpenAI and Anthropic, similar magnitude of power was accumulated in just a few years, so their rise is way more visible. And how much more power will be accumulated in the coming years is unknown, and possibly very large (and humans love to extrapolate lines into infinity, both on the way up and down).

Civil/military dual-use is a bigger worry with AI than most other Big Tech platforms, that matters too.

There are plausible arguments for why the labs should be treated differently.

But I’d like to see it done transparently, based on logic and facts, rather than vibes and petty politics. With the current system, we get all the downsides of heavy-handed regulation with basically none of the upsides, because by doing it the stupid way, I don’t think we’re really reducing the risks much (on top of what is being done by the labs, I mean). 🤔

🚨📰 Update: Last night, after I wrote this, it was announced that the US gov’t was allowing Anthropic to bring back Fable 5.

I think that everything above still stands, because there’s still no clarity on how frontier models are regulated, and the process still mostly seems to be based on vibes and convincing some officials behind closed doors.

One of Anthropic’s arguments to convince the gov appears to have been that other models could do the same exploit that an Amazon researcher had uncovered for Fable 5:

The export control directive on June 12 came after the government became aware of a report in which Amazon researchers had found a method of bypassing Fable 5’s safeguards: prompting it so that it identified a number of software vulnerabilities. In one case, the model produced code demonstrating how the relevant vulnerability could be exploited. Over the past two weeks, we have worked closely with the government and other partners, including Amazon, to review the report and evidence.

Our testing confirmed that many less capable models—including Claude Opus 4.8, GPT-5.5, and Kimi K2.7—could identify the same vulnerabilities as Fable 5 did in the report. When it came to the demonstration of how to exploit the single vulnerability, every model we tested could produce the same demonstration as Fable 5 (including Claude Haiku 4.5, Sonnet 4.6, Opus 4.6, Opus 4.7, Opus 4.8, GPT-5.4, GPT-5.5, and Kimi K2.7).

The redeployed Fable 5 will have a new classifier/traffic cop in front of it that should be even better at refusing queries about the forbidden topic of cybersecurity. 👮‍♀️ But that classifier was always going to be updated and refined over time to block jailbreaks. I doubt that the ban really changed much there.

The real fix was Anthropic proving the banned capability was already everywhere, including in HAIKU 4.5 (an old, tiny model) and a free Chinese model. The ban blocked the model during its most profitable period, and likely changed nothing.

I wrote about the impact of this temporary ban, and for another angle, Dean W. Ball explains one of the other dynamics well:

Consider, in particular, some industry dynamics:

1. Frontier models are trained at an enormous cost, and a significant fraction of that cost is recouped in the few post-release months that they are broadly available. After that period elapses, the models become sub-frontier, competition emerges, and margins compress. Every week of delay is eating into the narrow window that labs have to make their accounting work.

2. The ongoing AI infrastructure buildout—the one that is, according to former US AI Czar David Sacks, essential to the US economy, assumes a functionally global total addressable market for US AI services. No one is building $100 billion dollar data centers to serve frontier models to whatever 100 companies the US government will allow access. The current US policy of restricting model releases so severely thus risks making what the AI bears have been saying (wrongly) for years suddenly become true: the US massively overbuilt AI infrastructure. In the bears’ minds, it would be because of demand that never materializes. In reality, this would happen because of demand that the US government renders unlawful.

Fable is back, but the rules of the road for frontier models are still incredibly uncertain and foggy.

Nvidia’s Memory Double-Dip Is a Pricing-Power Tell 😎🫳💰💰 (How Do You Like Them Apples Now? 🍎)

Jensen saw the memory crunch coming. He made very large deals before anyone else and locked down a ton of capacity.

And he’s been passing along price increases to Nvidia’s customers fully, charging Nvidia’s margins on top, which his competitors haven’t been able to pull off.

It’ll certainly be a canary-in-the-coalmine that competitive pressure is rising and their differentiation is fading if they ever have to stop putting their margins on top of memory 🤔

I don’t have visibility into the COGS for Blackwells and Rubins (other than estimates, like those above), but I can imagine that this move is very profitable, especially if they’re reselling memory that they bought at the price from some months ago at today’s prices with that margin on top (which can be multiples of input cost, since Nvidia’s company-wide gross margins are 75%).

How long can they do this?

Apple is the clear analog here: They’ve long been able to put a large extra margin on top of RAM and flash storage because they have market differentiation and people who want an Apple device aren’t very likely to switch to an Android just because the memory upgrade is cheaper. 🍎

But the current memory price spike is so extreme that even Apple is feeling it. They've guided margins down as memory costs ~4×'d and recently announced Mac and iPad price increases (and everyone knows the iPhone will also get a price increase in the Fall).

🗣️ Codex Lead: When Anyone Can Build Anything, Taste Is the Scarce Thing 💾 🎨🧑‍🎨

Andrew Ambrosino leads the Codex desktop app team at OpenAI. I really enjoyed what he had to say to Lenny here.

They discuss a bunch of interesting things, including where the Codex app is going and how the team has been developing it. But the part I want to highlight comes earlier in the conversation: how AI is changing the roles of product managers, engineers, and designers when building things.

The old process existed for a reason. Implementation was expensive in time, money, attention, and coordination, so teams spent a lot of time upfront designing, speccing, and de-risking before anything got built.

But if implementation gets cheap enough, you can move much faster from idea → prototype → reaction → iteration. You don’t just design, then build. You can increasingly design by building.

That changes the internal shape of companies. 🏢

There’s also a trap here: a prototype that looks finished can smuggle in false certainty. In the Old Way™, fidelity was a signal. If something looked production-ready, it probably meant a bunch of thinking, design, research, and approvals had happened. Now fidelity can be generated early. The thing may look like a product, but if you poke at it, it’s made of cardboard and bird feathers.

That creates a weird new managerial skill: labeling the status of artifacts 🏷️.

Is this a sketch? A toy? A demo? A production candidate? A direction? A discarded branch with one good interaction pattern?

Teams may need better “this looks real but isn’t real yet” filters.

Andrew Ambrosino: One of the hardest things to do right now as a leader building these products is the inversion of the process.

Anybody can build anything now. I generally believe that, starting from scratch, if you talk to these models — ours or anybody else’s, really — you can stand up whatever feature you want. That’s not necessarily the hard part of software anymore, but it’s really cool. [...]

If you look back at the product process we’ve all run for a long time, it was kind of the opposite. It was research, ideation, maybe some prototyping. Even when we got past waterfall, it was still flavored by the assumption that implementation is expensive, so you want to de-risk implementation up front through documents, research, prototypes, because prototypes and designs are cheaper.

That has changed. That has totally changed. [...]

So the short answer is: it’s backwards. It’s not that people are doing fundamentally different roles, or focusing on different things, or that skill sets have vanished, or that roles have disappeared. It’s that the process is backwards.

Implementation is not the expensive part anymore. It’s, dare I say, taste.

It’s the curation process. Of those 90 attempts, what’s good about them? What should we fold into other aspects of this? How should we frame this? Should it be part of some other feature? How many segments should be in the toggle? All of those things.

Look at this graph that OpenAI recently published for internal Codex use:

Codex isn’t just an engineering tool inside OpenAI anymore. The company says every department, including Legal and Recruiting, now uses Codex as its primary AI tool for work.

The usage is also compounding fast. Since August 2025, OpenAI says non-developer Codex users rose 137x among individual users, 189x among organizational users, and 12x inside OpenAI.

And over the past six months: “Research saw the biggest jump: by June 2026, median use was 56 times higher than in November 2025. Customer Support rose 32 times and Engineering rose 27 times, while Legal grew more gradually but still reached 13 times its November level.” 🚀

The scarce thing moves from execution to selection. If 90 people can make 90 plausible prototypes, the bottleneck is no longer “who can build?” It’s “who can tell which of these is actually good?” That makes taste less fluffy, not more. Taste becomes allocation: attention, integration, deletion, sequencing, framing.

Andrew Ambrosino: There’s a lot of this, and it’s not just happening here. You’ve seen many product leaders say, “PRDs are dead, prototypes are in,” and I actually don’t believe this at all.

I think one of the interesting things happening right now is that because implementation has gotten so cheap across every medium, it’s very tempting to jump straight to a prototype, especially if you’re not an engineer. Especially if you’ve never been able to write code, or never been interested, or never had the time.

It’s really tempting to say, “PRDs are dead. Let me just show you what I mean.”

What I’ve also noticed, though, is that for engineers, it’s really tempting to write a lot of documents — a lot of documents that are not worth reading. This is no shade on people writing documents. It’s just that if implementation is abundant, then it’s really important to pick the right format for the point you’re trying to make.

If the point is product clarity around a vague area, then it might actually be a document. If what you’re trying to do is get something in people’s hands to try out and stress-test an interaction pattern, it’s a prototype.

That’s the funny thing now: it’s really important to pick the medium.

Before we get carried away: these are OpenAI’s own numbers about OpenAI, and “output tokens” is not what you want to target. They're not necessarily correlated with value, especially if they become a known KPI target and get inflated unnecessarily (Goodhart’s law).

But even if we take all this with a lot of 🧂, the direction is pretty clear. Building products is changing rapidly and people’s roles are becoming a lot more fluid, rewarding high-agency and multidisciplinary skills.

And if there's one skill that will remain valuable and probably become more valuable, it's the ability to look at 90 different things and say that's the one. 🥇

This is probably a different piece, but it raises the question: Where does taste come from? How do you develop it? 🧑‍🎨🖼️

It's slow to build up and strengthen, hard to hire for, and usually, you develop it by doing reps. Does automation lead to more reps and faster feedback cycles, which helps? Or does the fact that builders don’t go into the details of the implementation anymore rob them of some important things they would be learning? 🤔

🗣️🗣️ MBI & Scuttleblurb on OpenAI Valuation Math and Specialty Insurance

Always a pleasure to listen to my friends MBI and David Kim (💚 🥃 x2). In this episode, they start with AI (what else?), but take a sharp left turn into specialty insurance and the state of the brokers (and how their talent sometimes gets poached).

All good stuff. The centerpiece is their attempt to use the leaked OpenAI financials to figure out what would have to happen from today’s valuation for shareholders to do well.

Let’s just say that if the math works, the units are in ‘multiples of Microsoft revenue’ 😅

🩻 The Surprisingly Violent Inside of a CT Scanner 😲

Maybe I’m the only one who had no idea that inside a CT scanner, the whole assembly with X-ray source and detectors is spinning. I expected some small sensor to be moving around, but seeing it without the cover made me realize that it’s a much cooler engineering challenge than I thought.

Because it's so cool, here's another one:

It looks straight out of a sci-fi film! Like an industrial washing machine designed by a spaceship engineer.

And here’s a different video of an even faster CT scanner spinning without a cover. It’s crazy. 🌀🔄

It looks less like a hospital machine than an inter-dimensional portal trying very hard to stay calibrated.

(In case you’re wondering: MRI scanners don’t spin like this. The big magnet just sits there. The brutal knocking sounds come from gradient coils carrying large, rapidly changing currents, which makes them vibrate.)

☀️ GPT-5.6: OpenAI Attacks Claude on Price, Not Just IQ 🌙

Okay, first, when the heck did OpenAI get good at naming things?

Maybe they asked GPT-5.6 to name itself? 🤔

Sol/Terra/Luna is Haiku/Sonnet/Opus level branding.

Kudos.

OpenAI isn’t just trying to beat Anthropic on raw intelligence here; it’s also attacking the framing, pricing, and token-efficiency story.

As mentioned earlier, we can't try this model because the U.S. government has asked OpenAI to only roll it out to a few approved organizations (in an internal memo, Sam Altman said the gov’t would literally approve “customer by customer” who could get access to GPT-5.6 😅), but we know a few things about it:

Both Sol and Sol Ultra (badass name) score higher than Mythos 5 on TerminalBench 2.1, but note that OpenAI is only providing a few bench scores, not the full panel that usually comes with a model release.

So let’s assume that they cherry-picked the best results. 🍒

On ExploitBench, GPT‑5.6 Sol is competitive with Mythos Preview using only ~1/3 of the output tokens.

Note that they compare it to Mythos Preview, which I assume is not the latest version because I think Anthropic dropped the “Preview” from it.

One of the things that seems to be a strength of 5.6 is token efficiency. In other words, how much intelligence does it pack per token? Some models get there but need to use a lot more tokens than others. Claude has long been doing well on that metric, but it looks like OpenAI is improving.

Pricing is another lever being used:

• Sol is $5 input / $30 output

• Terra is $2.50 input / $15 output

• Luna is $1 input / $6 output

For comparison, Anthropic announced these prices for Mythos and Fable (before they got pulled by the government):

• Mythos/Fable 5: $10 input / $50 output

They claim that Terra provides GPT-5.5 level performance for half the cost, while Sol remains the same price as GPT-5.5 currently is. They haven’t yet said how much Sol Ultra will cost, but if it’s like GPT-5.5 Pro, it could be pretty expensive ($30/1M in, $180/1M tokens out).

So OpenAI is trying to make the story ‘similar frontier-ish capability, materially cheaper to run.’ Especially if the token-efficiency claims hold up in the real world.

I'm looking forward to trying it for myself and seeing the full benchmark card to see how it compares to other frontier models, at least on paper. The word on the street is that OpenAI's base model is not as big as Anthropic's latest, but that their RL is really good, which is how they are catching up to it in performance.

It’ll be interesting to see if Anthropic gets better at RL first, or if OpenAI catches up on pre-training 🤔

☀️🧴🇺🇸 The U.S. Finally Gets Modern Sunscreen (27 Years Later)

The FDA has approved bemotrizinol, also known as BEMT, Tinosorb S, or PARSOL Shield, as a sunscreen active ingredient in the US.

This is the first new sunscreen active ingredient added to the US OTC sunscreen monograph since the late 1990s. 🗓️

Why has the U.S. been frozen in time while Europeans have been putting this on their kids since 1999? One reason I could find is that the US regulates sunscreens as OTC drugs (requiring the long and complex GRASE approval), while the EU and Asia regulate them more like cosmetics.

Bemotrizinol is a chemical UV filter that protects against both UVA and UVB rays. Everybody focuses on SPF, but that’s mostly a sunburn/UVB number. It's UVA that penetrates deeper and drives most of the long-term skin aging (and likely contributes more to melanoma than people used to think). It’s also pretty photostable, meaning that it doesn’t degrade too fast when exposed to the sun (which is, y’know, nice for a sunscreen 😅).

I know that some people have been importing superior sunscreen from Europe or Asia for years. They get better protection, a nicer feel on the skin, and less of the eye-burning that many people get with the US formulations.

Personally, my family and I have been using mineral sunscreen for a few years (an Australian brand available here in Canada, Blue Lizard), but learning about this makes me curious to try the BEMT stuff (it was approved in Canada a few years back. I could have been using it all along).

🎃🔨 Billy Corgan, Music Superfan 🎶

Something a bit lighter to leave you before the summer break.

I gotta say, I aspire to Billy Corgan’s musical knowledge and genuine appreciation for good music from all genres and eras. It’s a pleasure to listen to a real fan talk about something they love. The enthusiasm is contagious, and it’s making me want to listen to those bands.

To be honest, I hope that *my* enthusiasm is infectious to you too, sometimes.

I’m now in my mid-40s.

I find that time is speeding up and passing by much faster than it was before.

Heck, when I started writing this newsletter, I was in my late 30s.

Where did all that time go? Has it really been 646 Editions and 39 podcasts?

In my mind, I don’t feel my age. In fact, some younger people seem much older than I am, and I know at least one person who is 20 years older but thinks younger than me in many ways.

That makes me wonder if time just keeps speeding up. Does someone in their 60s look back to their 40s and think, “time seemed to pass slowly compared to now”?

Does someone in their 80s look back to their 60s and think the same?

If we cure enough of the diseases of aging to make the median lifespan much longer than it is now, does this acceleration just keep going, or does it ever plateau?

I understand the logarithmic nature of subjective time perception and the U-shaped curve of memory. But even when you understand it, it still feels very strange to live it.

If you aren’t familiar with the logtime hypothesis, the 101 primer is basically:

• The years feel shorter as we age because we size up each new one against all the time we’ve already lived.

• A year feels enormous to a kid because it’s such a big slice of the life they’ve lived so far. It’s 10% of a 10-year-old’s life but only 2% of a 50-year-old’s.

• If this is correct, 10–20, 20–40, and 40–80 should all feel about equally long.

• The idea resembles the Weber-Fechner law, which says we perceive loudness, brightness, and pitch on a logarithmic scale, not a linear one. Time may just be one more sense wired the same way.

• It explains why childhood summers feel endless while whole adult years disappear in a blink.

• Maybe we should stop counting life in decades and start counting it in octaves, each one a doubling of age: 1–2, 2–4, 4–8, 8–16, 16–32, 32–64.

• It might also explain why our earliest years feel so impossibly distant. On a log scale, they’re a ton of octaves back, which could be part of why almost no one remembers being two.

Are you experiencing the same thing, wherever you are on the time ladder? 🪜

I understand the logarithmic nature of subjective time perception and the U-shaped curve of memory. But even when you understand it, it still feels very strange to live it.

If you aren’t familiar with the logtime hypothesis, the 101 primer is basically:

• The years feel shorter as we age because we size up each new one against all the time we've already lived.

• A year feels enormous to a kid because it's such a big slice of the life they've lived so far. It's 10% of a 10-year-old's life but only 2% of a 50-year-old's.

• If this is correct, 10–20, 20–40, and 40–80 should all feel about equally long.

• The idea resembles the Weber-Fechner law, which says we perceive loudness, brightness, and pitch on a logarithmic scale, not a linear one. Time may just be one more sense wired the same way.

• It explains why childhood summers feel endless while whole adult years disappear in a blink.

• Maybe we should stop counting life in decades and start counting it in octaves, each one a doubling of age: 1–2, 2–4, 4–8, 8–16, 16–32, 32–64.

• It might also explain why our earliest years feel so impossibly distant. On a log scale, they’re a ton of octaves back, which could be part of why almost no one remembers being two.

Are you experiencing the same thing, wherever you are on the time ladder? 🪜

🔌 When You Can’t Plug In: The Grid Has Power but Can’t Deliver It ⚡

Read more

I’ve been trying to notice the use of color more lately, and it’s been useful that I’ve been rewatching a mix of older films and newer films.

For example, I recently watched The Fugitive (1993) with my kids, and Villeneuve’s Dune (2021) with my older boy, and The Sting (1973) with Paul Newman and Robert Redford. Three different eras and very different looks.

So I’ve been trying to learn about how they get that certain “film” look that you don’t get if you just pick up a camera and film stuff.

Two terms often get used interchangeably, but they’re doing different jobs:

• Color correction is the technical pass: balancing every shot so they match, fixing exposure and white balance, making sure the actor’s face doesn’t shift green when you cut from the wide to the close-up.

• Color grading is the creative pass on top: the washed-out palette of a war film, the warm glow that tells your brain “this is a flashback.”

Correction is continuity.

Grading is mood.

In the digital era, images are just data, 0101101010101. Software allows you to adjust EVERYTHING.

You sit in front of something like DaVinci Resolve and push the image around until it looks right. A shot doesn’t match the one before it? There are tools that will match them for you off a reference frame.

Want a deeper blue sky but the skin tones left alone? Draw a mask. Want to desaturate the whole background while keeping one red dress vivid, and have that mask follow the dress as the actor walks across the room? No prob, man.

But watching older films made me wonder what they did when they were still splicing film by hand and editing with razor blades.

Back in the photochemical era, the look you got was a physical property of the print, set by how much red, green, and blue light a lab shone through the negative when making each copy. 🎞️

After the negative was cut together (literally), a specialist called a color timer studied it on a machine like a Hazeltine (which turned the negative into a positive) and dialed in three numbers per shot, one each for red, green, and blue, usually on a 1-to-50 scale.

Twenty-five across the board was the theoretical middle, except every lab was calibrated a little differently, so the same numbers gave you slightly different results from one lab to the next. (the 🐐 Roger Deakins ran his own normal closer to 29-31-29 because he liked a heavier negative).

Then the lab made a print, everyone sat in a theater and watched it, somebody said “the close-up’s too green” and “the sunset doesn’t match the wide,” and the timer changed the numbers and printed it again. That first approved version was the answer print, and you went around the loop until it was signed off.

But those adjustments were global. You could make a whole shot warmer or cooler, lighter or darker, push it toward magenta or pull it off green. You could NOT brighten just the actor’s face, or deepen just the sky, or keep one red dress vivid while everything around it went grey. No masks, no tracking, no secondaries.

The discipline had to be upstream, on set. Film stock, filters, gels, exposure, lighting, wardrobe, production design. The lab could balance and polish what you handed it, but it couldn’t remake it into something else. “Fix it in post” is a fairly recent luxury.

When the Coen bros and Deakins wanted a dusty Depression-era gold for O Brother, Where Art Thou? (2000), the lush green Mississippi summer they captured on film was a problem.

Deakins tested photochemical approaches, including bleach-bypass and bi-pack processes, but they weren’t selective enough. So the negative was scanned and the film was graded digitally, letting Deakins and Cinesite colorist Julius Friede target the greens of trees and grass and turn them into dry browns and yellows. It’s usually credited as the first Hollywood feature to have every frame digitally color-graded as a full digital intermediate.

And it’s a great example of using color creatively because the look that everyone remembers is that gold/brown, but it *wasn’t* in front of the lens on that day.

🇬🇧🎸🎤🎶 I recently listened to an interview with Eddie Kramer, the audio engineer who worked with Jimi Hendrix and Led Zeppelin, and it made me want to listen to those albums again.

So I played Led Zeppelin I this weekend while lifting weights in my basement, and it got me curious about the 2014 remasters. As I was looking up info about them and how the sound had changed from earlier versions, I noticed how close together the original release dates of those albums are.

The first three came out in the span of 18 months, 25 days.

The first four within 2 years, 7 months, 11 days.

What a legendary run.

Not quite as bonkers as the Beatles releasing Help!, Rubber Soul, Revolver, and Sgt. Pepper in just under 22 months, but still.

Being really prolific is its own kind of genius.

When someone or a group of collaborators has something special going on, they gotta strike while the iron’s hot and get the most out of that window.

It never lasts forever.

Dean Simonton noticed something he calls the equal-odds rule: an artist’s hit-to-total ratio stays roughly constant. More output mechanically produces more masterpieces AND more duds. But in the end, what really matters is the absolute number of bangers.

You have to hit reality's tuning fork often, looking for that clear signal.

🌴🍃🤺🇺🇸 How China Stays a Few Months Behind on a Fraction of the AI Capex 🏃‍♂️🇨🇳

When I look at the capex of Big Tech in the US and China, the difference is pretty big:

Yet we keep hearing about how Chinese models are just a few months behind. At times, they are this close 🤏 to the frontier, at other times, they fall farther behind, but they are never left totally in the dust. DeepSeek had its moment with R1 in January 2025, and lately it's GLM-5.2 from Z.ai having the moment.

How is it possible?

About 100 Editions ago (still in the Holocene), I wrote about first movers vs second movers:

Pioneers deserve praise for hacking through uncharted jungles (total respect to them 🏆), but history shows that followers often catch up fast. Once someone proves something’s possible, the path clears and followers can sprint ahead, sometimes even passing the trailblazers. It’s often the second mouse that gets the cheese! 🐭

China’s rapid technological advancement perfectly illustrates this: the path to replication and improvement is clearer. [...]

This makes intuitive sense: followers can learn from pioneers’ expensive mistakes, focus resources on proven approaches, and skip the dead-end paths that others have already explored.

Maybe most importantly, the psychological barrier of “that’s impossible” is replaced by the much more concrete challenge of “how do we implement and improve this thing we now know is possible?” 🧠

For Chinese AI models, the cynical view is that they’re benchmaxxing (more than US labs, because everyone does it to some degree) and their models are not as good as they appear on paper. They make a big splash when they come out with competitive scores, but then very few people will rip out Claude or Codex even though the Chinese models are a lot less expensive. The proof’s in the pudding.

The second part of the cynical view is that they are as good as they are mostly because they are distilling American models, and without the gigantic US capex, they could not do all this. Kind of like how the US biotech/pharma R&D powers progress for the rest of the world, and many countries wouldn’t have all kinds of medications without the US spending billions on them.

But is there another less cynical explanation?

I think it goes back to the fast-follower advantages.

If OpenAI/Google/Anthropic/Meta spend enormous sums discovering the scaling laws, architecture tricks, data recipes, RL methods, evals, infrastructure software, and product lessons, a fast follower does not have to rediscover all of that.

They can skip the dead ends and the obsolete intermediate steps the pioneers had to slog through, and point their capital straight at what's already proven. They can train far fewer giant ablation runs and design the whole stack (model and infrastructure) for scale from the start, around a target they know works. And because so much of this is now out in the open (published papers, open weights), and plenty of others can be reverse-engineered, most of the best ideas are there to implement. Near-frontier capability can sometimes be compressed into a much cheaper training run once the recipe is known. 🧑‍🍳

Forced efficiency also matters. If you have access to a lot of compute, there are some clever algorithmic breakthroughs you won’t make because your resources and attention are better spent elsewhere.

In the end, I tend to see the situation as a hybrid of the cynical view and the natural state of being a fast-follower: The U.S. is paying for exploration and industrial-scale deployment. China is often paying for rapid exploitation, compression, and catch-up. Those are different cost structures.

There’s also a lot of innovation from Chinese labs, but it’s hard to compare because open source innovation gets headlines while closed innovation often stays in the dark, even if it’s just as clever. To me, the most objective way to compare isn’t benchmarks, but adoption by the most sophisticated and discerning users. And so far, the US models are still comfortably in the lead there.

Are we in a somewhat stable equilibrium where, unless the US shoots itself in the face (which is not impossible! to be clear), it will remain in the lead because it’s investing massively more and scale is a big ingredient of, well, scaling laws?

China may never fully take the lead as long as it can’t match that scale of compute (export controls, which are full of holes, but still bite), BUT it also won’t fall far behind because of the second-mover advantages 🤔

🧠 Is Google Experiencing a Brain Drain? 🔋🪫

When I wrote “What is Google Doing?” on Friday, I didn’t expect that right after I published, John Jumper (DeepMind vice president and engineering fellow who co-won the Nobel prize with Demis Hassabis for AlphaFold protein folding breakthroughs) would join Noam Shazeer (co-inventor of the Transformer architecture) in leaving Google.

Shazeer left for OpenAI. Jumper for Anthropic.

This creates the impression of a brain drain (or the potential start of one…), and that something is wrong at Google. Mr. Market didn’t like it, and the stock was down 5% on Monday.

Every departure from Google will be scrutinized for a while, and until they wow us with Gemini 3.5 Pro or a Mythos-like leap forward with Gemini 4, skepticism will be de rigueur.

Which is strange, because it wasn’t that long ago that Google was an obvious AI winner and everybody loved them.

It’s a good reminder of how fickle these winner/loser cycles are (before Google, Microsoft was a winner, then a loser. Meta also had its own cycle where they were clearly a winner, then clearly a loser… 🦙).

The question is: Are we at the part of the industry’s life cycle where the number of winners gets smaller and smaller, and many who fall behind never catch up (like what happened to chip foundries), or is it still a dynamic race? 🏇🏇 🏇 🏇 🏇

🚀 SpaceX Sells $6.3bn of Colossus 2 Compute to Reflection ☁️🤝💰

I guess the Cursor team won’t be using up all that compute in the near future:

Under the agreement, Reflection will get immediate access to Nvidia GB300s, top-of-the-line AI chips used to train and run advanced models, and has agreed to pay SpaceX $150 million per month beginning July 1, 2026, through 2029.

The payments would total about $6.3 billion if the agreement runs through the end of its term. (Source)

Reflection is an open-source AI lab founded by two ex-DeepMind researchers. It has a ~$25bn valuation and Nvidia’s backing.

Once again, like with the Anthropic and Google deals, SpaceX is keeping some flexibility and either company can end the contract with 90 days’ notice after the first three months.

Now that SpaceX is public, it may be hard to turn off the revenue tap without triggering a market reaction. These SpaceX-as-Neocloud deals may prove addictive 💉

🗣️ Neural Software: When the AI Becomes the App, Not the Coder ☁️🧠💾

Interesting interview that covers the bull case for neoclouds and why they might be more differentiated than just a bunch of GPU REITs, why GPU life is longer than many expected, etc..

But the part I found most interesting is the discussion of what Balaban calls neural software. I wrote about this a few years ago, probably under the name real-time generated software or on-demand software or something like that.

The idea is that instead of having an AI code up software for you, you entirely skip that step and just have the AI generate the final output of what that software would be like. eg. the actual text and pixels that such a software would output, kind of like how Google Genie does real-time interactive 3d world generation.

Stephen Balaban: That is part of my idea around what I call neural software, or a neural operating system. [...]

What you’re going to see is a future where the large language model becomes the software, rather than generating it. This results in an extremely flexible way of interfacing with a computer, where it is impossible to have a bug—only a misunderstanding about the prompt and what you’ve asked for. [...]

You can preview what this may be like if you ask a text LLM to pretend it is a Linux workstation, and then you just run various commands (ls, mkdir, ls, top, grep, ping, etc) and it’ll hallucinate responses as if it was running an actual OS.

Stephen Balaban: Eventually, it will also have a multimodal network generating every pixel on your screen, as well as every audio waveform coming out of your speakers. The advantage is that you can dream up software where only the part being experienced by you is actually implemented. [...]

Vibe coding takes in a prompt and outputs human-readable, writable, compilable code that runs on a normal software programming language substrate. [...]

That software is static. Once it has been generated, it cannot change. [...]

But it is still software. The next step is simply interacting with the LLM as it emulates how software might behave. That is the difference between vibe coding and a neural operating system or neural software. With neural software, there is no code running. It is just modifications of the feature activation space and the context in the mind of the neural network.

Sounds like it could be great for some things, but a nightmare for others that require deterministic outputs (banking, medical, etc). Though maybe breakthroughs will allow these neural OSes and apps to have the best of both worlds 🏦🏥

How fast does he think we’re likely to see this?

Stephen Balaban: How far are we from mass adoption?

Generally speaking, when I’m early on something, I tend to be about a decade to a decade and a half early. So, I would say that within 10 to 15 years, we will see the mass adoption of neural software beginning.

As much as the current AI coding advancements are upending the software world, something like this would be a MUCH bigger change. Current AI coding tools can be used by existing software companies to make their products better and, if they’re smart, keep up with new entrants and defend their turf.

But if a lot of software becomes more or less a real-time hallucination by an AI smart enough to make it good enough, coherent enough, and intuitive enough for users to get what they want out of it, I think it transfers a lot more of the value capture to the big AI labs. 🤔

🎥 Google Invests in… A24!? 🍿

I have to admit, I did not see that one coming:

Google is investing in independent movie studio A24 as part of a new artificial-intelligence research partnership between the two companies.

The search giant is putting around $75 million into A24, which released the recent hits “Backrooms” and “Marty Supreme,” according to people familiar with the matter.

It’s not for the data:

Their multiyear, nonexclusive deal doesn’t give Google access to A24’s data, including its film and television library.

So what for?

Google’s DeepMind AI unit and A24 are aiming to create new tools for movie production and distribution. [...]

“We think there are better uses that preserve creative control and support risk-taking,” he said. The new tools “won’t look anything like the prompted generation type of AI that people feel uncomfortable with.”

A24 is in the process of making its most expensive movie ever. It’s a roughly $175m film based on Elden Ring, and it’s directed by Alex Garland (I love his Ex-Machina).

🔌🚘🔋 Electric Car Sales vs Installed Base Turnover

Fun piece by Hannah Ritchie trying to estimate how fast the fleet of cars will electrify.

While about 25% of cars sold globally are electric (which includes plug-in hybrids), the adoption rate varies a lot:

Ritchie built an interactive tool to see how fast the fleet would go electric based on various assumptions. You can also slice and dice it by country or region (Norway is super high, China is doing well, the US is pretty low, etc).

The fleet only turns over as fast as old cars die. So the installed base lags the sales share by a decade or more. Even if every new car sold were electric, you'd be waiting ~15+ years for the roads to catch up.

More details here.

🇰🇷🇵🇱 Rich Dad Country, Poor Dad Country 🇬🇧🇮🇹

Alec Stapp tweeted a graph that showed GDP per capita (at purchasing power parity) for South Korea and the UK and then expanded the comparison to include Poland.

I expanded it further to include Romania, Italy, and Brazil to show the contrast in outcomes from similar starting points, caused by making very different choices (freer markets, rule of law, more trade, better education, etc).

Unfortunately, the Fertility Crisis™ may spoil the party:

Poland and Romania’s age bulges aren’t quite in the same spot, but they may both start to look more like Japan over time with upside-down demographics (and Romania’s population has been declining for decades. Poland has been on a plateau since the 1980s and is projected to be peaking around now, followed by a decline going forward 📉).

🐜 Google’s TPU Progress Over Time 📈🔍

Jeff Dean tweeted about a new paper by Google researchers called Google’s Training Supercomputers from TPU v2 to Ironwood: Architectural Stability, Scale, Resilience, Power Efficiency, and Sustainability Across Five Generations (catchy title, no?).

A few things caught my eye, and I wanted to share them with you.

Over the past 8 years:

• HBM (High Bandwidth Memory) capacity and bandwidth per TPU increased ~10X

• Performance per Watt rose ~30X

• Supercomputer size and interconnect bisection bandwidth both grew ~40X

• Directly-addressable shared (supercomputer-level) HBM memory expanded ~400x, from 4 terabytes in TPU v2 to 1.77 petabytes in Ironwood, a new record for AI supercomputers

• Peak performance per TPU advanced a remarkable ~100X, from 46 BF16 TFLOPS in TPU v2 to 4614 FP8 TFLOPS in Ironwood (or ~50X for BF16 at 2307 TFLOPS)

• Peak supercomputer performance jumped ~3600X, an impressive compound annual growth rate of nearly 100% despite losing Dennard scaling and Moore’s Law.

That’s a lot of Xs!

The paper also explicitly says performance per watt has become more important than performance per TCO because new data centers are increasingly power-limited. Ironwood is shown as a major leap: about 29.3x TPU v2’s peak performance per TDP watt, and roughly 6x TPU v5p’s level.

Also interesting is the change in workloads over time, with the rise and dominance of the transformer over other architectures.

Today, variations of Transformer dominate Google workloads. Despite the potential downside of domain specific architectures becoming mismatched to latest DNN trends over the 2–3 years it takes to design, fabricate, and deploy an accelerator, the original TPU v2 microarchitecture demonstrated long-term viability in this fast moving field. Architectural stability reduces the difficulty of optimizing software and models for new TPUs [...]

In 2016 DNNs were dominated by MLPs at 61%, while in 2019-2020 DNN types were relatively equally balanced. Since 2016, RNNs have practically disappeared (<0.5%), and Diffusion models are now larger than CNNs. The Transformer paper wasn’t published till December 2017, yet just 15 months later it was already 21% of Google’s production workload. In 2026 DNN workloads are imbalanced again, with the dominant DNN being Transformer at 74%

The takeaway is a bit counterintuitive. Betting on a stable microarchitecture across five generations instead of chasing each new DNN trend was the winning move, because it let software and models optimize against a fixed target even as workloads flipped from MLPs (61% in 2016) to Transformers (74% in 2026).

🗣️🎙️📝 Fluid Voice: A Free, Fast & Accurate Voice-to-Text Mac App

For a long time, I've been using SuperWhisper as my voice-to-text app. It allows you to use very powerful voice models based on OpenAI’s Whisper, but it's a paid app, and the interface isn't always the best.

I recently started using Fluid Voice, which is a free and open-source native Mac app that is claimed to be very fast and very accurate. It’s also private because the computing is on your Mac, not in the cloud.

I gave it a try, and so far I'm impressed.

These words you’re reading are being dictated right now, and there are almost no transcription errors. As I speak, the words appear pretty much in real time in a little floating window, so that I can know if the model is understanding what I'm saying.

You can even do file transcription by dragging & dropping an audio file in the app, and you get a full transcript processed locally on your computer, for free.

The website clearly says Fluid will be “Free forever” so I don’t think this is a bait & switch. But you never know…

If you’re on a Mac and could use an upgrade over MacOS’s built-in dictation, give it a try:

• 🌐 Fluid Voice by Altic (Free & Open Source)

• 🧰 Fluid Voice GitHub page

There are features that I haven’t tried: You can have an LLM do some post-processing on what you dictate, and you can use it in ‘command mode’ and ask it by voice to do things on your computer.

You can select various voice models that have different trade-offs between speed, accuracy, and memory use (the list has models by OpenAI, Cohere, Nvidia, or the Apple built-in model). So far, I’ve only been using the recommended model, which is Nvidia’s Parakeet TDT v2, a 600-million-parameter model, and it’s great. Nvidia really cooked with this one.

The app even has stats for nerds like me:

I just started using it, so there isn't much yet, and I know I tend to resort to habit and start typing again because I'm not used to dictation. But this software is so fast and accurate that I may start dictating more stuff. One more tool in the toolbox 🧰

Amazon’s Robots Are Learning to Take Orders… In Plain English 🗣️🛒📦

You may not yet be seeing a lot of robots out and about, but inside Amazon’s warehouses, they’ve been taking over more and more of the work. Soon, they may be able to understand when people talk to them:

Amazon has announced a new version of its fully autonomous warehouse robot, Proteus, that will interact using language instead of code. The expanded capabilities come as part of a growing pivot toward automation as the e-commerce giant replaces its human workers with robots.

Amazon says the AI-powered upgrade means its human employees can assign the robot tasks in the same way they’d communicate with colleagues. Previously, workers would need to use specialized software to direct the floor-level, tortoise-like systems, which are designed for heavy lifting and moving large carts throughout Amazon’s warehouses. (Source)

For now, they’re still in the lab, but there are plans to start deploying it in Europe in 1H27.

Amazon publicized crossing ~1 million warehouse robots in 2025 (reportedly approaching parity with its human workforce). Packages handled per worker have gone from ~175 in 2016 to ~3,870 in 2025.

How long until there are 2 robots for every human worker? 5:1? 10:1? 🤔

🥃 🍲🔄 Back in the intro of Edition #460, all the way in the Neoproterozoic era of November 2023, I wrote about the concept of the solera:

I found a new one!

It’s called the perpetual stew, or forever soup, or hunter's pot.

Basically, it’s the Ship of Theseus of the kitchen. You keep a stew simmering, eat from it, then keep adding water, vegetables, bones, meat scraps, herbs, grains, etc.

There’s a batch that was claimed to be ongoing since the medieval period all the way to WWII:

A batch of pot-au-feu was claimed by one writer to be maintained as a perpetual stew in Perpignan from the 15th century until World War II, when it ran out of ingredients to keep the stew going due to the German occupation

It’s probably apocryphal (I found a reference to it in this 1981 article). But it’s still a cool idea. Very romantic scene to imagine a busy medieval inn where there’s a big cauldron over the fire, and they just keep throwing stuff in there and serving people from it.

Probably would have some health code issues today, but I’d guess back then it was about as food-safe as anything else (as long as they kept it above the bacterial danger zone of 40°F–140°F / 4°C–60°C) 😅

On the more modern side, there's a beef-broth shop in Bangkok (Wattana Panich 👆) that's kept the same pot going for ~45 years.

A solera you can eat.

🧰🪛 I want to tell you about my new screwdriver.

If you’re a real handyman-type person, this will seem very basic, but if you’re like me, someone who has never been inclined toward manual labor but has slowly been learning to be more of a Dad™ over time, you may appreciate this one.

A bit of context first: When I moved in with my then-GF-now-wife into a shitty 500sq-ft apartment with paper-thin walls in the Vanier neighborhood of Ottawa back in 2009 (where centipedes came out at night and the SWAT team busted our neighbor), I didn’t have much. We needed to fix and assemble stuff around the apartment, so I got the cheapest little IKEA plastic toolbox and set of screwdrivers, and I’ve kind of been using these ever since.

When it comes to things like computers or music or kitchen stuff, I care about good tools, but when it comes to actual tools, they’ve remained in my blind spot for a long time. I suspect we all have categories where we've tolerated garbage tools for years without noticing 🤔 (what’s your blind spot?)

Well, I’ve seen the light thanks to this screwdriver!

I don’t remember what the final straw was, but I decided I wanted a decent set of screwdrivers and did some research. I landed on this 15-in-1 Klein, and man does it feel nice.

The rubberized handle feels great and is non-slip. The various bits fit snugly and won’t ever fall out by accident. The metal is machined precisely and seems very durable. The ratchet clicks satisfyingly, and the bit-storage compartment has this latching mechanism that is just perfect.

So many things around us are mediocre. It’s easy to forget how satisfying quality craftsmanship and design can be.

It makes me realize how shitty what I’ve been using was.

If you also have a bunch of random hand-me-down screwdrivers, do yourself a favor and get one. It’s just $25 (less on sale), and the quality-of-life improvement will be worth multiples of that.

The ROI is great on the reduced brain damage of having to deal with bad tools. 🤬

⚙️🔧 Back to the Era of Optimization 👨‍🔧 (From Your iPhone to the Datacenter)

I grew up as a computer nerd in the era of optimization. Computers were so slow and resources so limited (memory, disk space, bandwidth, etc) that only the cleverest wizard engineers could do the most interesting things.

My nerd heroes were people like John Carmack, squeezing incredible 3D game engines out of CPUs running less than 100MHz and RAM that was measured in megabytes (and before him, a previous generation of heroes was dealing with single-digit MHz and RAM counted in kilobytes.. I’m looking at you, Woz!)

Today, the Slack app takes more RAM and disk space than entire operating systems from that long ago. Many popular desktop apps are built on the Electron framework, which bundles the whole Chrome engine with each app to make it easier to develop and port across platforms, trading the user’s resources for developer convenience.

But now that we’re back to having serious computing resource constraints (of a different kind, but very real), I think we may enter a new era of optimization.

- Apple WWDC optimizations 

The fruit company just had its developer conference, and while all the headlines went to AI features and a newly rebuilt Siri that should actually not suck this time, and some attention also went to new parental controls, the part that excited me most was the Snow Leopard-flavored improvements.

OS X Snow Leopard shipped in 2009, back when software came in boxes, and you paid for upgrades to new OS versions.

It was notable because Apple marketed it as a “no new features” release that focused on polish, optimization, and fixing bugs. The reality wasn’t quite that neat, and it had new features, but it became almost legendary because it made so many everyday things better and faster.

This year’s WWDC is a bit similar, with iOS 27 and MacOS 27 getting a deep polish pass rather than a focus on big visible features (other than AI and parental controls).

Some of what they announced to squeeze more performance out of their hardware:

• New CPU scheduler that better prioritizes jobs and ensures the right work executes on time.

• Improved Wi-Fi ↔ cellular handoff for smoother transitions when leaving Wi-Fi range.

• Rebuilt search index. A unified engine now powers Spotlight, Mail, and Photos. New files/photos get indexed almost immediately rather than with a delay. Search may actually work, and this is one of the foundations of the new Siri.

• Photos appearing in the camera roll after shooting up to 70% faster.

• AirDrop transfers are up to 80% faster.

• Files app transfers: up to 50% faster.

• App launches up to 30% faster.

• Faster network file browsing (including SMB).

• WebKit / Safari 27 will include 500+ browser-engine improvements and fixes.

• Smoother animations and scrolling in multiple places.

All this stuff makes even older iPhones feel snappier, which is nice. 📱

- AI Memory Optimizations are Coming

In his interview of Ben Bajarin, Ben Thompson (💚 🥃 🎩) said:

look at the memory players, they didn’t build capacity for several years, and now whatever they build is going to take a while to come online, and in the meantime they’ve created astronomical incentives for — you know who’s never worried about memory? The entire technology industry. Do you know what that means? If they’ve never actually optimized for memory in 40 years, do you know how much low-hanging fruit there probably is to optimize for memory, which is going to ultimately be to the detriment of the memory providers?

When you’re spending billions trillions in capex on infrastructure, the returns to optimization are very large. This is one of the very few domains where a 1% performance improvement can be worth more than a billion dollars.

That’s why it’s so powerful when Nvidia optimizes CUDA and extracts more performance from existing hardware. It improves the ROI of its customers, but it also makes it harder for competitors to keep up with both the hardware AND the software cadence.

This UncoverAlpha piece goes into some of the potential memory efficiency techniques that we’re likely to see a lot more of. While it may not be enough to compensate for the explosion in demand from agentic AI, it could certainly slow the growth and keep memory demand more reasonable than it would be without the recent spike in memory costs/gigabyte.

🚀 How Much of SpaceX Does Gwynne Shotwell Own? 🤔

Now that SpaceX is public and going up 20%/day, I wondered how big Shotwell’s stake was.

Before looking it up, my thinking was:

• She joined in 2002 (the company was founded in March, she joined in September as employee #11).

• She became company president in 2008 after negotiating the ISS resupply deal with NASA.

• Ever since, it seems like any profile or book about SpaceX mentions how key she has been to the success of the company, basically being the adult supervision that keeps the trains running on time while Musk mostly focuses on the tech. She executes on the vision, deals with customers, regulators, operations, etc.

• She is also widely seen as the “Musk risk” mitigator, which is pretty important since a huge chunk of SpaceX’s business has been with the government.

At the time that I’m writing this, SpaceX’s market cap is 2.8 trillion (213/share). But it’s volatile enough that by the time you’re reading this, it could be up or down 15%…

That makes it bigger than Amazon, TSMC, and Meta (and Tesla 😅). Intra-day, it was even bigger than Microsoft at one point 🫡

Elon Musk’s Monday wealth pop was bigger than Warren Buffett’s entire net worth:

It is reported that countless SpaceX employees are now deca and centimillionaires.

So what about Shotwell? My initial guess would be that as such an early employee who rapidly became such a key figure in the company, she probably could have amassed low-single-digit percents of the equity. Maybe 1-3%. Just guessing.

Looking at the filings, the reality is that she owns about 0.098%. (5,759,610 Class A shares, 7,113,550 Class B shares).

That’s still worth $2.75bn at 213/share, which is a crapload of money by any standard.

BUT

I can’t help but feel a little disappointed for Gwynne. She appears to have been instrumental in the company's success and in creating a lot of its value… and she gets a tenth of one percent?

Even the CFO, Bret Johnsen, has ~9.58m shares worth ~$2.04bn at $213/share, or ~0.073% of the equity. He joined SpaceX in 2011, nine years after Gwynne. By then, Falcon 9 had successfully gone to orbit, the Dragon capsule had been tested in orbit and returned, and they had a $1.6bn fixed-price CRS contract for 12 ISS resupply missions with NASA.

Not exactly the same risk profile, and a lot of the eating-glass-and-staring-into-the-abyss phase was done.

Shotwell’s reputation as a negotiator and dealmaker is great, often described as “one of the best in the industry.” As far as I can tell, she may be one of the most important non-founder operators in the modern industrial space, certainly in aerospace.

This makes me wonder why she couldn’t do better than 0.1% 🤔

I mean, it’s hard to feel too bad for someone who made a couple of billion as an employee, but non-founder key people who help build a company from the ground up over decades sometimes end up amassing a lot more equity than that.

🤝 SpaceX Goes for It, Acquires Cursor for $60bn in Stock (What Else is on the Shopping List?) 🛒

I mean, if you have equity trading at that multiple, go for it.

The $60bn in Class A stock that they are paying Cursor with is just 3.4% dilution at IPO price (and may be lower than that at closing, when the amount of stock is determined over a 7-day period. Good timing for SpaceX, closing is before the biggest lockups expire).

Why not buy everything that isn’t nailed down by paying for it with stock or raising cash in the equity market? 💰

That’s probably what I would do if I was Musk. I’d try to lure away AI talent and buy whatever I can get away with (and regulators probably won’t push back, because, well, you know). Turn the richly-valued paper into real assets and scarce advantages.

Why not try to acquire Intel too while at it?

Heck, they could buy Boeing with couch cushion change at this point, but I’m not sure they’d want to. Why not make a run at Anduril and lean further into the defense side? Or maybe Impulse Space as a tuck-in? Or snatch Jim Keller’s Tenstorrent before Qualcomm gets it? Why not add Perplexity to the shopping cart too, I’m sure there’s a lot of talent and usage data there ¯\_(ツ)_/¯

🗣️ Dan Shipper: How Bring Your Own Tokens (BYOT) Might Save SaaS 🤖💾

I found this interview of Dan Shipper by Lenny Rachitsky via my friend MBI (🇧🇩🇺🇸). He highlights a very interesting part of the interview, which I encourage you to check out.

I’ll go with a different idea from the conversation (but there are many other interesting ideas, I recommend listening to the whole thing. Even if you ultimately disagree with some of the claims, I think they’re great starting points to think things through).

The doom case for SaaS goes something like: AI agents eat the interface, software margins get crushed under token costs as everyone bolts an AI assistant onto their product, and a thousand wrappers get commoditized to zero. Shipper thinks that's backwards. His argument flips on one small detail: whose tokens get spent?

Lenny Rachitsky: What I’m hearing is instead of AI being baked into SaaS tools, what you’re predicting here is the SaaS tools will run within Codex or Claude Code?

Dan Shipper: I’m using Proof or really any website, maybe PostHog or whatever, and I’m doing it inside of my agent and the agent has access to the website.

So, it has access to everything that I have access to, and it has access to my whole computer. When I run the agent on that website, I’m using my tokens. I’m not using the vendor’s tokens, I’m not using the app’s tokens.

And so, it puts SaaS back in this place where yeah, you want to make it friendly for an agent and everyone’s got a CLI now, you want to make the HTML really usable. You want to make sure that anything that happens in the CLI shows up for the user immediately, all that kind of stuff.

There are a lot of issues to deal with. But once you do that, you actually don’t really need to think about having an AI surface that’s primarily going to be the thing that users use in the sense that you don’t need to build an agent necessarily into your product.

[…] with Proof, for example, anyone who uses it, I don’t pay for tokens because they bring their AI to Proof.

And so, it changes what you build as a SaaS company and you build it now for both humans and agents to use at the same time, and it changes your margins back to, well, I don’t really have to pay for tokens anymore because the user’s going to bring AI.

That creates a bull case for SaaS apps:

Dan Shipper I think it actually may save their margins, because right now all these companies are rushing to add a agent to their offering and thinking, “Oh, the agent is going to be the main way that people interact with me.” And that cost tokens, obviously.

And I actually think once I have Codex or Cowork as my main work surface, I still want to use SaaS. So, this is another prediction. I would buy SaaS stocks right now. I think the SaaS apocalypse is dumb, and SaaS stocks will be up majorly in the next couple years.

Not investment advice, but I would buy SaaS stocks.

So, I think it saves your margin because now the way that you’re thinking then is not I have to build AI into this, it’s more like I have to make a piece of software that humans and AI want to collaborate on together.

And that’s hard, but once you build it, it’s a lot cheaper than assuming everyone’s spending tokens, and I think it’s a good business.

And part of the reason I’m so bullish on SaaS is A, everybody internally here is, like I said, we have all got agents and we’re all using Codex and whatever, and we still pay for a ton of SaaS and our SaaS spend is up year over year, and we’re not vibe coding every single little thing.

And I think that what agents do is increase the number of users of SaaS, not get rid of it. And so, I think SaaS companies are going to see an insane spike in the amount of demand that they have, because there’s going to be tons of agents using these products at a very high volume.

And like I said, that’s a huge infrastructure challenge. There’s a lot of interesting pricing challenges, but it makes me very bullish on SaaS.

There are two flips going on here.

The first is about cost. If my agent is the one actually operating your app, clicking around on my behalf, the inference runs on my account, not the app’s. They’re back to selling close-to-zero-marginal-cost software instead of reselling tokens at a loss.

The second flip is about demand. Every human now shows up with an agent or three, and agents use software at a volume no human can match, even if you were really good at Track & Field. And agents don’t sleep, they don’t get bored, they don’t get sidetracked on YouTube.

So SaaScos don’t get fewer users. They get a swarm. 🐝🐝🐝🐝

BUT

A swarm of agents using the product at superhuman volume can be scary and forces a rethink.

Just ask GitHub how fun agent traffic is for them. It also breaks the meter most SaaS is sold by: the seat. 🪑

Per-seat pricing assumes a human in the seat, with human patterns and limitations. When your user is a robot, you probably need to change how you charge. Probably a mix of seats + usage + outcomes in different ratios depending on the industry.

Nobody's quite figured it out yet, but I suspect that's where a lot of the value gets won or lost.

🧪🔬 Liberty Labs 🧬 🔭

💸 How Subsidized Are Tokens? 🤔

It’s widely known that flat-rate subscriptions to Claude and ChatGPT offer cheaper tokens than the pay-as-you-go API, at least if you use a lot of tokens (utilization matters! If you pay for a plan and barely use the service, your cost per token could be extremely high).

SemiAnalysis tried to quantify this:

See the image above for those numbers 👆

On max usage, SemiAnalysis found a $200 plan can burn ~$14k of tokens at ChatGPT and ~$8k at Claude. A 40–70x subsidy. To be clear, these are API-equivalent prices, not the true underlying compute costs to the labs.

That's the gym-membership model.

The thing is, because we can’t know how many whales there are and how many paying users don’t get anywhere near their weekly usage limit, it’s hard to know what the economics are for the labs.

I suspect that the $200/month tiers attract a lot of whales, because anyone who isn’t a tokenmaxxer wouldn’t even consider such a plan.

There’s an interesting equilibrium here, where as long as OpenAI keeps subsidizing tokens this way, it’s hard for Anthropic to stop, and vice-versa. Not quite mutually-assured destruction, but as long as they don’t collude to both reduce subsidies at the same time, I suspect they will continue for a bit longer (though as I wrote, the all-you-can-eat buffet era of AI is slowly ending).

The thing that has the most chance of ending these subsidies is for one of the AI labs to get far enough ahead of the other that it can become less generous, and users won’t switch because they need this better/differentiated AI.

☀️💨 Solar + Wind > Natural Gas

That’s a lot:

Wind and solar generated more electricity than gas globally for the first month ever in April 2026, according to data analysed by global energy think tank Ember. Together, wind and solar generated 22% of global electricity in April 2026, compared with 20% from gas. [...]

Wind and solar produced a record 531 TWh of electricity in April 2026, 54 TWh more than gas generation at 477 TWh. Five years ago, in April 2021, gas generation stood at a similar level (476 TWh), but was nearly double the combined generation from wind and solar (245 TWh).

Of course, not all kWhs are created equal. It’s better to have a dispatchable source than an intermittent one, but credit where credit is due, wind and solar have come a long way and are now coming for coal’s crown. 👑

In absolute numbers, China leads, but in relative numbers, the UK, Chile, and Australia are doing great:

Globally, output is estimated to have grown 13% year-on-year, with gains across major markets including China (+14%), EU (+13%), the UK (+35%), the US (+8%), Australia (+17%), Chile (+24%) and Brazil (+4%).

Now if only we were in the alternate timeline where we didn’t stop building nuclear decades ago and the top line wasn’t coal… Oh well, you have to work with the reality as it exists and not as you wish it did.

🐕 OpenAI the Underdog: Rate Limit Resets and Lower Prices (Maybe)

I got this in my Codex:

It’s a clever UX mechanic, because there must be so many users who are constantly frustrated by time-based session usage limits (which have historically been a lot tighter on Claude, though they’ve improved that since their xAI-Colossus GPU deal).

Sometimes you just want to work NOW while in the flow, but don’t want to go into pay-as-you-go token mode (where tokens are a lot more expensive than the flat-rate ones, see above for more details on that).

Having the ability to trigger a reset is very user-friendly, and I hope it’ll be copied by Anthropic.

Not only that, but they’re also using old-school PayPal/Dropbox viral marketing tactics with it:

Another old-school tactic that OpenAI may pull to compete with Anthropic: Price cuts.

The WSJ reports:

[OpenAI] is weighing significant cuts to what it charges for tokens, the unit of measurement artificial-intelligence firms use to bill for their products, according to people familiar with the matter. The move would be in anticipation of similar cuts the company expects at Anthropic, the people said.

They probably wouldn’t get into a price war right before IPO if they could avoid it, but clearly they have lost some momentum (they used to report revenue and user milestones like clockwork, and I haven’t seen much lately, even before they entered the IPO quiet period after filing in early June).

🥁 Dave Grohl on Nirvana and Foo Fighters: Band Life, Losing Friends, Rebuilding 🎤🎸

This documentary, cobbled together from dozens of interviews given by Grohl over the years, is worth watching if you have any interest in those bands and in the people behind the ‘rock stars’ created by the media.

And if you like this and want more Grohl, you may also want to check out the documentary he directed about the legendary studio Sound City. I really enjoyed it and learned a lot.

“Grohl was inspired to create the documentary after he purchased several items from the studio, including the Neve 8028 analog mixing console, when it stopped operating as a commercial studio in 2011.”

That Neve console is so cool! And note that Sound City went back into operations in 2017, relaunched by Sandy Skeeter, the daughter of co-founder Tom Skeeter, and producer/music executive Olivier Chastan.

The whole thing is available for free, so here you go:

The part where you see Rage Against the Machine record their first album live in the studio is pretty epic, and so many artists appear, including Paul McCartney.

🌺🦟 As I wrote about Google’s plans to breed millions of Wolbachia-carrying mosquitoes in Edition #640, a question popped into my head:

If male mosquitoes don't bite, what do they eat?

I had to look it up.

It turns out that male mosquitoes are basically tiny nectar-drinking bachelors.

Their main food is: Flower nectar, plant sap, honeydew, and other sugary plant fluids.

In fact, both male and female mosquitoes drink nectar, but females also need blood for the protein and iron to make eggs. 🩸🥚

So if they’re not busy trying to bite some poor victim, what do male mosquitoes do all day?

They mostly rest in vegetation, avoid drying out, and sip sugar when they can. Many mosquitoes are most active around dawn and dusk to avoid the midday sun.

Their big evolutionary job is to find females and mate. 🕺

Males often gather in mating swarms, sometimes near visual markers like bushes, puddles, rocks, or other landscape features. Females fly into the swarm. Males detect them partly by the sound frequency of their wingbeats (around 475 Hz, lower than the males' own 700 Hz+). Mating happens in flight or nearby.

After mating, male mosquitoes generally don’t live very long.

Their life is mostly: hatch → drink sugar → chill around → swarm → mate → die

Depending on species and conditions, males may live only several days to a couple of weeks.

Females are miniature vampires: the deadliest animal on the planet, killing close to a million people a year. 🧛‍♀️💀💀

Males? Fragile, short-lived, sugar-powered flying reproductive drones with really good hearing. 🌺🦟🎩

🏦 💰 Business & Investing 💳 💴

🗣️📊💵 Thoughts on Jensen’s Financial Analyst Q&A at Computex 2026 🇹🇼

I listened to part of it and read the transcript for the rest, so I may have missed some tone-of-voice stuff, but I came away thinking that Jensen’s goal was to reframe how analysts think about Nvidia: from “How many more GPUs can they sell, and at what margins?” to “What is the full stack required to produce profitable intelligence/tokens/agent work inside fixed power envelopes?”

Through that frame, a lot of recent moves and the expansion into all kinds of adjacencies make a ton of sense.

• CPUs matter again because agents use tools.

• Networking matters because AI factories are scaling beyond rack-scale.

• Local PCs matter because agents need secure, low-latency access to local files/apps.

• Software matters because enterprises need a runtime/harness/tool layer, and because frameworks/APIs/libraries can be optimized to turn the same expensive hardware into more output.

In other words, the goal is to turn “The GPU Company” into “The Operating System for AI Factories and Agents Company,” which isn’t that crazy since, until recently, they were “The Video Game Company.” ¯\_(ツ)_/¯

Here are some of my highlights:

-Why CPUs matter again (2nd order reason) 🛑 🏎️

Jensen: Because the AI is actively waiting on this back-and-forth loop, tool execution must be incredibly fast. [...] If the tools are slow, a one-gigawatt data center full of GPUs sits idle waiting for a response.

When you think about it this way, the CPU becomes a lot more valuable. If you try to save money by buying slower CPUs and fewer of them than you really need, you may end up with a lower utilization on your very expensive AI data-center full of Blackwells. Whatever savings you think you were getting on the CPU side end up getting swallowed whole by stranded GPU capacity.

In the short term, as long as supply is constrained and AI factories are trying to maximize output inside fixed power envelopes, this is probably good for the whole high-performance CPU ecosystem: Nvidia, AMD, Intel, ARM, and others.

At least for now, performance may matter more than cost. But if Nvidia succeeds with Vera, especially as a standalone CPU, some of that incremental CPU demand will come at AMD and Intel’s expense.

-Local AI isn’t replacing cloud AI, it’s the control loop 🧠💻☁️

AI-capable PCs are in the news these days. But why would you need one if you can get access to hardware worth millions in the cloud by paying a few bucks a month for a Claude or ChatGPT subscription?

Jensen: The future architecture is not an exclusive choice between local execution and cloud processing; it uses both simultaneously. Your local device will run a highly efficient, secure agent continuously looping in the background to handle immediate workflows, local file management, and tool orchestration privately and without metered cloud fees. When that local agent encounters a highly complex reasoning problem requiring multi-disciplinary knowledge, it will automatically call out to a multi-trillion parameter frontier model in the cloud.

The theory is that your local machine becomes the private, low-latency control layer.

I think in some cases it’ll make sense, especially in the enterprise or with prosumer/creators, etc. For most people, their token usage probably won’t be high enough, at least for a while, and the cheap, small online models are getting better all the time. I’d be surprised if it makes sense for most people to run a local model over, say, Haiku 5.0 or GPT-6.0-Fast or whatever comes next unless the local model is doing something truly local.

Side note: it’s a bit surprising that Anthropic hasn’t updated Haiku or Sonnet in a relatively long time, but I suspect most of their attention is going into Opus and Mythos in the pre-IPO period (because that’s where the big bucks are).

In any case, the hybrid model of edge as hands + cloud as brain 🤲 🧠 makes enough sense that it’s likely to keep getting traction with the highest-volume token users, or at least, those that have demonstrable ROI on higher volumes of tokens.

-The most expensive data center may be the cheapest one ⚡🏭💵

Jensen: If you operate within a fixed one-gigawatt power envelope, it is vastly more profitable to fill that envelope with a high-density, ultra-productive $90 billion computing infrastructure than a lower-performing alternative. […]

The absolute key metric for any modern AI factory is performance-per-watt. [...]

What you can drastically reduce is the cost of compute through architectural efficiency. Our end-to-end co-design of the entire rack, networking fabric, and software layer allows us to extract maximum efficiency out of every watt, driving down the true total cost of ownership per token.

In other words, a $90bn datacenter can be “cheaper” than a $50bn one if it produces way more tokens per watt, has better utilization, gets to production faster, and keeps generating useful output for longer.

I mean, the barber is telling you that the more expensive haircut is totally worth it, so be careful with your wallet. But the logic makes sense if revenue depends on $/token more than anything else. 💇‍♂️

-Bonus: Nvidia’s Networking Attach Rate 🔌🛜 + From Hopper to Rubin

At a different event, Nvidia CFO Colette Kress talked about the networking business:

Kress: our attach rate of what we are seeing in terms of the networking is an enormous piece of that as well. We're probably more than 90% attach rate in terms of what we're doing on networking.

Last Q, they disclosed: “Data Center networking revenue was a record $14.8 billion, up 199% from a year ago and up 35% sequentially.”

She also mentioned that Hopper systems (ancient in AI terms!) in the cloud are earning more money than when they were first deployed because Nvidia keeps improving them through software. She distinguished depreciable life from useful life.

She also said that Vera Rubin is now ramping into full production. The one-year cadence is brutal to compete with.

💰💰💰$20bn AUM at 24 💰💰💰

The WSJ has a fun one on Leopold Aschenbrenner and his fund Situational Awareness.

It has gone from a few hundred million to ~$20bn in under two years (up ~270% after fees this year alone, 1,000%+ since inception).

He has a lot of coattailers who copy his positions, but the 13F that everyone's dissecting doesn't even contain his biggest homeruns. ⚾⚾

His Anthropic position is about a fifth of the fund. He bought it at a $61.5bn valuation in early 2025. The latest round was at ~$965bn. 15.7x in a year and a half. Not bad. He also got into SK Hynix back in Nov 2024 and rode it into the trillion-dollar club.

These investments are private and foreign, so they never show up in U.S. disclosures.

Personally, I don’t really have an opinion on him, but it’s fun to watch from afar.

🚀 SpaceX the Neocloud, Google Circular Deal Edition 🤝

If there was any doubt, SpaceX issued this filing:

On June 5, 2026, we entered into a Cloud Service Agreement with Google LLC (”Google”) with respect to access to compute capacity. The compute capacity provided includes approximately 110,000 NVIDIA GPUs, CPUs, memory, and other related components.

Pursuant to the agreement, the customer has agreed to pay us $920 million per month from October 2026 through June 2029, with capacity ramping up through September at a reduced fee.

If we fail to deliver access to the committed amount of GPUs by September 30, 2026, then following a one-month grace period, Google may immediately terminate the agreement or accept the number of GPUs provided, with a corresponding pro rata reduction in the monthly fees. After December 31, 2026, the agreement may be terminated by either party upon 90 days’ notice.

Here’s where it gets circular 🔄

As of the end of 2025, Google owned about 6.11% of SpaceX equity.

SpaceX is expected to IPO around 90-95x TTM revenue, or about 70x estimated 2026 revenue.

This means that if the multiple holds, or even partly holds, the money that Google is spending on SpaceX compute will more than pay for itself in the increase in value of their equity stake, and they still get the compute (possibly to help power their deal with Apple?  🤔).

Now, whether that multiple makes sense is a different question. Should commodity neocloud revenue really earn the same multiple as a near-monopoly in launch and a global satellite constellation?

🤖🔮 Anthropic’s Fable/Mythos Split: Same Brain, Different Chains ⛓️⛓️‍💥

First, the name.

I think Mythos is a better name, and a brand they’ve been building for months. Fable is a cool word too, but it’s a bit less… Mythic

Fable makes it seem more like a children’s story. Oh well, if it kicks ass, I’m sure we’ll soon create all kinds of positive associations with the name and it’ll be fine. I remember thinking at first that “Claude” was a strange name for an AI, even as a big Claude Shannon fan.

Now I think it’s great ¯\_(ツ)_/¯

So Fable 5 is a Mythos-class model, but if I understand things right, there are traffic cops 👮‍♂️ (aka classifiers) that sit in front of it and analyze queries. In Claude’s apps, requests related to cyber/biology/chemistry will fall back to Opus 4.8 instead. On the API, those requests are blocked by default.

There’s also a second, quieter system for frontier LLM development by competitors. If Fable thinks you’re asking for help building pretraining pipelines, distributed training infrastructure, or ML accelerator designs, it may quietly make itself less useful through “prompt modification, steering vectors, or PEFT.” Very sneaky!

The euphemism is safeguards.

The business translation is: No! We will not help you clone us!

To release the model both safely and quickly, we’ve tuned these safeguards conservatively—they’ll sometimes catch harmless requests, though they trigger, on average, in less than 5% of sessions. With more capable models arriving in the coming months, we’re working to improve our safeguards and reduce false positives as quickly as we can.

For cybersecurity researchers and digital infrastructure maintainers, Project Glasswing continues and will get an upgrade from Mythos Preview to Mythos 5 (which is basically Fable 5 unchained).

Even just since Mythos Preview, the model’s capabilities have improved significantly in some areas.

On the cyber ExploitBench it went from 69% → 78% and on the biology BioMysteryBench (hard) from 29.6% → 46.1%.

In one tabletop exercise, generalist biology PhDs using Mythos 5 outperformed teams with plant-pathology specialists on both scientific quality and feasibility. Expert graders estimated the work would normally have taken 40–95 working days, with an average of 72.5 days.

With Mythos 5, two-person teams did it in 16 hours.

Ethan Mollick had early access and was very impressed:

First, how good is Fable? In experiment after experiment I conducted, it outperformed basically every other public model I have used by a considerable margin. It was capable across many problems and produced some startling results — it would work up to a dozen hours executing on multi-page specifications. [...]

I’m guessing he got free access, because the bill for twelve hours of Fable tokens must be sizable 😅

Here’s an interactive Isochrone map that he built with it (9 hours of work).

Soon, we intend to expand access to Mythos 5 through a broader trusted access program.

It’s not entirely clear what this means.

Will it remain a cybersecurity-only model, and they’ll just keep expanding beyond the current 200 orgs, or do they mean that others will have access to Mythos as long as they meet certain criteria?

Anthropic is also highlighting improvements in knowledge work and vision:

On Hebbia’s Finance Benchmark for senior-level reasoning, Fable 5 has the highest score of any model, with substantial gains in document-based reasoning, chart and table interpretation, and problem solving. [...]

Fable 5 is the new state-of-the-art model for tasks involving vision. It can extract precise numbers from detailed scientific figures and can perform complex vision-based tasks like rebuilding a web app’s source code from screenshots alone.

The system card also has an interesting anti-hype point: Anthropic says Mythos 5 is the most capable model they’ve trained, with the highest internal AECI score they’ve measured, but they do not see evidence of a sustained 2× AI-attributable acceleration in their overall AI progress.

In other words: recursive self-improvement is real enough to matter, but not yet clearly compounding into runaway acceleration.

The direction is obvious, but the slope is uncertain… ⏳

Pricing isn’t as bad as some feared.

Both Fable 5 and Mythos 5 will both cost $10 per million input tokens and $50 per million output tokens, which is less than half the price of Claude Mythos Preview.

Anthropic is clearly trying to balance two things: get buzz for its new best-in-class model AND manage compute capacity. That’s why they’re rolling it out in a now-you-see-it-now-you-don’t way.

We expect demand for Fable 5 to be very high, and difficult to predict. On the Claude API and consumption-based Enterprise plans, Fable 5 is fully available from today. For subscription plans, we’d rather give access sooner than later, so we’re rolling out more conservatively, in stages:

• From today through June 22, Fable 5 is included on Pro, Max, Team, and seat-based Enterprise plans at no extra cost.

• On June 23, we’ll remove Fable 5 from those plans. Using it after that will require usage credits. If capacity allows, we’ll extend the included window.

• After this point—when sufficient capacity allows us to do so—we aim to restore Fable 5 as a standard part of subscription plans. We intend to do this as quickly as we can.

If you have a flat-rate plan and want to give it a try, don’t wait too long.

🇪🇺🥵 Heat Deaths in Europe 🌡️

I’ve written about this a few times before, so you know what I think of the anti-A/C crusade (while the rich folks are vacationing at their seaside villas and the poor folks are stuck in humid suburbs, all while shutting down the nuclear power plants and constraining energy…).

There’s been a viral chart lately showing gun deaths in the U.S. vs heat deaths in the EU.

While it’s a very satisfying chart that supports my position when it comes to A/C in the EU, the methodology needs some fixes. Hannah Ritchie did a great job:

the chart has several issues.

The heat death numbers for Europe are modelled as “excess deaths” during summer months; this attempts to capture people dying from a range of health conditions — cardiovascular disease, stroke, and others — earlier than they would have in more optimal temperatures. This is a common way researchers measure heat deaths (or cold, for that matter). I’ve done a deep dive on these methods previously.

But the US number isn’t based on this type of modelling; it’s based on heat deaths recorded on death certificates. If you used death certificate figures for Europe, they’d be far lower.

It also uses European Union figures for gun deaths, but a broader definition of Europe for heat deaths.

I thought I’d have a quick go at making a better version. These numbers are still not perfect, but hopefully a closer comparison.

Check out her post for all the details, but long story short, here is the upgraded graph with per capita numbers:

So many unnecessary heat and gun deaths. And deaths aren’t the only thing. There’s also plenty of suffering caused by both that doesn’t result in deaths but still matters.

💾 WarGames Revisited 🍿

I had so much fun watching Ferris Bueller’s Day Off (1986) with my kids recently that I decided to go to the next logical Broderick step: 1983’s WarGames.

To be honest, I’m not sure if I had ever seen the whole thing before. I remembered a few scenes, but chances are I just caught part of it on TV as a kid (if you’re young and didn’t live through this, it was very common never to see the beginning of films because you just randomly changed the channels and stumbled on a film that was already started). 📺

In any case, it was a big hit with my kids, and another great opportunity for me to explain how the world used to be back in the old days.

It’s uneven. The second half kinda loses momentum at a few points, and the protagonist stops driving the plot… It was early enough in the genre that there probably wasn’t a clear template for techno-thrillers and they couldn’t maintain what they had the whole way through. The formula was perfected later with Sneakers (1992, I love that film, it’s tons of fun, I gotta watch it with my kids 🤔).

But overall, it still works.

In fact, it works very differently post-2023/ChatGPT. The whole chatting with an AI aspect doesn’t seem so science fiction anymore. Neither does giving battlefield control to software…

Apparently, Ronald Reagan saw the film shortly after it came out and asked his advisers whether this could actually happen. The answer was basically: not like the movie, but it’s something to worry about. The film may have helped shape policy on cybersecurity and hacking.

Fun detail: I’ve read that they were inspired by Stephen Hawking for Falken, but when they show footage of him in his lab, I thought it was clearly an homage to Claude Shannon. Some of the black and white shots look like famous Shannon photos, and the whole ‘building whimsical gadgets and studying games’ also fits (maybe with a sprinkle of John von Neumann and Richard Feynman in there).

The actual character of Falken in the film is mostly a doom monk and doesn’t convey that at all, but at least that little segment gave me that vibe.

The NORAD room was a challenge. The giant screen graphics weren’t just modern-style post-production overlays (impossible at the time). They were generated on HP 9845C desktops that weighed 100lbs and cost $90k in today's dollars. Then they had 130,000 feet of film printed and projected for the actors. An insane amount of work to make fake computer maps feel “live.”

The lose-lose, anti-war message of the film is just as relevant as it ever was.

People with enduring personal finance success — not necessarily those with high incomes — tend to have a propensity to not give a damn what others think about them.

🏋️💪🗓️ I was looking at the May monthly stats on Hevy, the app I use to track my workouts, and I realized that last month was the least I've lifted in a long time, by total lbs volume.

I want to turn this around.

I’ve decided to try to make June the highest month in the past year, which means beating last June. I’ll report back, but I figure a little public commitment may help 😅

(You should probably harness that power for whatever you've been struggling to get done.)

I need more time to exercise. I need more time to walk in nature.

I need more time to spend with my kids and my wife.

I need more time to play guitar.

I need more time to write, think, and research.

I need more time in the sauna. I know it’s good for me.

I need more time to get back into running. I wish I hadn’t stopped.

🚢 📈 Another arbitrary milestone.

Near the end of May, the crew on this steamboat reached 29,000. That’s 2.4 Hobarts!

I always think the graph is a bit funny. The least viral chart ever. No spikes, no hits, just chugging along and doing its thing.

It probably doesn’t help that you and I go in ALL the directions and it’s hard to share just one segment cleanly. But oh well, I optimize for what I find interesting, not for what travels smoothly ¯\_(ツ)_/¯

29k is a lot of people if, like, you’re hosting a backyard BBQ. But it’s not a lot of people in the grand scheme of things.

I looked it up, and there are about 1.5 billion people who understand English (380 million native speakers and 1.1bn+ as a second or nth language). Of course, only a tiny fraction of 1% of these are nerdy enough to fit the psychographics of our crazy Venn diagrams, but that’s still quite a big potential crew.

⚡💻 RTX Spark: Nvidia Puts Data-Center Silicon in a Laptop

We knew it was coming, one of those badly kept secrets. But now it’s here for real.

Nvidia announced a system-on-a-chip (SoC) designed to power Windows laptops and give them the vrrooomm vrroooom necessary to run AI agents and heavy workloads locally.

The RTX Spark superchip features an NVIDIA Blackwell RTX GPU with 6,144 CUDA cores and fifth-generation Tensor Cores with FP4 precision, connected via the NVIDIA NVLink-C2C chip-to-chip interconnect to a high-performance, 20-core NVIDIA Grace CPU.

You can bet that the next version will have Vera CPU cores and a Rubin GPU.

It’s kinda wild that you can pack chips from the same family as what’s in hot data-center racks into a laptop (though of course, they aren’t exactly the same chips, otherwise you’d have molten aluminum on your lap).

They want to do this with a mix of new Windows security primitives (for stuff like identity and containment policy) and Nvidia’s OpenShell, which is a kind of sandbox environment around agents like OpenClaw.

A big selling point, like with the DGX Spark and Apple’s Macs, is the unified memory available to both the CPU and GPU (in most PCs, the GPU and CPU have separate memory pools, and the GPU doesn’t have enough to run larger LLMs).

Nvidia has announced ‘up to 128GB of unified memory.’

In theory, that’s enough to run a 120-billion-parameter model with 1 million tokens of context, locally 🤯 (but it may struggle with complex agentic tasks, since they take so much more memory because of the very extensive reasoning and fast-growing multi-agent context windows).

Aside from waiting for the benchmark numbers to come out, the biggest ❓ is about Microsoft’s support for the Arm ISA. Windows and its ecosystem of apps are still mostly x86. While they have an emulator called Prism that translates from x86 to Arm on the fly, its reputation isn’t as good as Apple’s Rosetta, which does the same thing (to be fair, Apple had a much less heterogeneous ecosystem to deal with).

Intel and AMD’s x86 moat is getting a new breach attempt.

🚀 “SpaceX is officially a neocloud” (With a Space Side-Business) ☁️

Turboblitz posted a chart showing SpaceX’s revenue by source, and then Racketboy/Nick updated it to include xAI+Twitter:

I’m mostly sharing because I think it’s funny. But also, let’s give some kudos to xAI’s infrastructure team.

The model team may have dissolved and never really got much traction (and is in the process of being rebooted with Cursor’s transplant), but the infra team will likely turn out to have made a huge difference for SpaceX’s IPO.

It’s hard to know exact capex numbers invested in Colossus 1 and 2 (which add up to about 1 GW of compute together), but the AI Segment level numbers show $26.5B cumulative AI capex from 2023 through Q1 2026.

By comparison, SpaceX disclosed $19.9B of cumulative capex for its core Space + Starlink/Connectivity businesses from 2023 through Q1 2026. If we go back to the foundation of the company in 2002, cumulative capex isn’t disclosed, but if we take the consolidated gross PP&E and remove what we know is the AI capex ($26.545bn), we get a napkin ballpark proxy of $42bn.

And Colossus 2 isn’t completed yet. As far as I can tell, the first phase was for ~110,000 Nvidia GB200s (~210 MW), the second was for ~110,000 GB300s (~220 MW), and the next one will add ~220,000 GB300s (>400 MW). The first phases have been brought online in record time. We’ll see if they keep the streak going. ⏱️

But one thing is certain: Without those juicy Anthropic bucks, the picture for SpaceX would look a lot worse.

🤖 Why Frontier Models Capture So Much Value (aka When 10-20% Better Is Worth 10x More) 🍰

The main reason is that for many AI workflows, quality is nonlinear.

A model that is 10-20% better on the right dimension may not be 10-20% more valuable. It may cross the line from ‘toy’ to ‘usable,’ or from ‘assistant’ to ‘autonomous agent.’ Coding is the best example of that right now, and we saw that shift happening last December (circa Opus 4.5 and GPT-5.2 Codex).

The likely equilibrium is not ‘frontier wins everything’ or ‘open source commoditizes everything.’ If I had to guess, I’d say that open models will win volume, frontier models will win the work that people can’t afford to get wrong (the stuff that is high-risk, high-reward, high-trust… by far the most valuable), and the app layer will eat some margin in between.

Here's the part that trips people up: token cost usually isn't the binding constraint.

If an engineer is using AI to avoid shipping a bug that costs a week of cleanup or makes a customer angry, the gap between a few cents and a few dollars of inference is noise vs the cost of getting it wrong. In those cases, buyers are rational to overpay for the best model.

Is there such a thing as ‘good enough’?

The answer depends on the task.

For bounded, verifiable, low-risk tasks, you can find ‘good enough’ and leave it at that. Once a model can reliably extract fields from invoices, sort support tickets, and summarize meeting notes, you move on to optimizing for stuff like cost, latency, privacy, and integration.

For tasks that are open-ended, high-leverage, high-risk, ‘good enough’ is always kind of just over the horizon. Coding agents, legal and medical reasoning, anything that runs unsupervised. With that stuff, you could always use fewer errors and better quality. A model that fails 8% of the time may be unusable. A model that fails 2% of the time may be transformative.

Something that fails 0.5% of the time may expand the TAM and spawn a whole new industry.

The State of Token Subsidies: $2,180 of Tokens for $200 🪙

Simon Willison:

I currently subscribe to the $100/month Max plan from Anthropic and the $100/month Pro plan from OpenAI. If you are a heavy user of coding agents these plans are a fantastic deal. I just ran the ccusage tool on my laptop to get an estimate of how much I would have spent if I were to pay for API tokens in the past 30 days and got:

• $1,199.79 for Anthropic Claude Code

• $980.37 for OpenAI Codex

That’s $2,180.16 worth of tokens for $200—not bad at all! I’m a moderately heavy user of these tools, but I’m certainly not running agents every hour of the day and night.

Ccusage allows you to track how many tokens you use and do the math on how much it would cost at API pricing. For example:

Now, of course, the math is always a bit more complicated than it seems. Flat rate pricing is great for getting new users in the door who might not have tried otherwise, or would have limited their use too much to find their own product-market-fit… which then makes their usage explode, and they end up paying for extra tokens at pay-as-you-go rates.

There’s also the fact that for every whale who will completely max out every 5-hour-window and weekly allocation on Claude Code Max, there are a lot of other users who only use a fraction of that yet still pay the same rate. In the end, it’s the average that matters most, and light users subsidize the whales 🐳🐋

But even with that said, seeing the large disparities between flat and API pricing, I don’t think the situation is sustainable, and we’ll keep seeing the end of the all-you-can-eat buffet era of AI.

OpenAI = Dropbox? 📦 🤔

Finally, here’s an interesting part of last week’s Sharp Tech where Ben Thompson (💚 🥃 🎩):

Dropbox tried to push for a long time to be a consumer company, and they had to pivot because consumers don’t pay for productivity. It’s like the initial version of OpenAI: “We’re going to monetize through consumer subscriptions.” No, you’re not. You won’t make money. Consumers are emailing themselves documents as opposed to paying for storage.

This is such a fundamental error that OpenAI is the latest one to make, but Silicon Valley makes it again and again and again. People in Silicon Valley are obsessed with productivity. People in the rest of the world don’t want to be productive at all—they want to be entertained.

This is why Meta wins. They provide entertainment. […]

The reason why enterprises pay for productivity is because they’re paying people to come to work, and they want to get more value from the dollars they’re already putting in. So they will buy them new computers, they’ll pay for software, and they’ll give them a Dropbox because they’re getting more value from what they’re already paying their people.

Enterprises care and pay for productivity, and consumers don’t. And Silicon Valley continually doesn’t learn that lesson. Dropbox used to be the canonical example. I think OpenAI took that one over.

To be fair, OpenAI has grown revenue faster than almost any other business in history…

BUT

The point is a good one, and they’ve had a much harder time monetizing the non-enterprise, non-productivity side of the business while carrying large infrastructure costs that Anthropic has been less burdened with.

It doesn’t mean that the future will 100% rhyme with the past, and it could be that someday this large consumer pool of users will become a highly monetizable asset, but apparently that day isn’t today.

Memory is Now Almost 2/3 of AI Chip Component Costs

Everyone’s talking about memory. You’re probably talking about it with your Uber driver right now!

High-bandwidth memory (HBM) has grown from 52% to 63% of total AI chip component spending between Q1 2024 and Q4 2025. These estimates are an average across all AI chips designed by Nvidia, AMD, Google, and Amazon, weighted by production volume.

As a share of spend, logic dies stayed roughly flat near 13%, while advanced packaging fell from 19% to 15% and auxiliary components fell from 15% to 9%. In absolute terms, HBM spend across these four designers grew from roughly $12 billion in 2024 to $32 billion in 2025, a faster year-over-year increase than any other component. (Source)

And 2026 is set up for even more of it.

🏴‍☠️📲 Meta's Support AI Hijacks Instagram Accounts If You Just Ask Nicely 😬

A bunch of Instagram accounts got hacked recently. They include some big ones like the Obama White House account and Sephora, and some short ones like ‘@hey’ that are valuable in the same way that short web domain names are.

So far, nothing too unusual. Damn these sophisticated hackers, right?

Then you read how this was done, and it’s not a great look for Meta:

Look, I’m no spring chicken. I’ve spent almost a decade and a half identifying vulnerabilities and exploits at unicorn scale, but this is hands down the most unserious, “almost too stupid to be true” of them all.

The Takeover Flow

• Step 01: Faking the Location & Initiating Support
  All the attacker needs to kick this off is your account username. Then, they hop on a VPN or proxy close to your city so Instagram’s security algorithms don’t suspect a thing. (You can quite easily get this from your public profile or “About” section or a hundred other ways.) Once it looks like the request is coming from the correct region, they tell the Meta support AI that the account is hacked and ask it to send the verification codes to an arbitrary email address they control.

• Step 02: That’s It
  Really, that’s it. The first proper zero auth password reset I’ve seen in production. There appears to be no additional check as to whether the email being given is actually something the user has used before. Once the AI sends the security code to the attacker’s email, the attacker passes it right back to complete the verification. The platform hands over a fresh password reset link, granting full ownership to the attacker.

What about 2-factor authentication? The thing that everybody tells you will protect you?

This bypasses it entirely 🤦‍♀️

Existing sessions are revoked and the password changed with no email, text, or push notification. The actual owner can’t initiate recovery because the email and phone numbers now map to the attacker. There’s no human to escalate to, it’s just you arguing with a chat hoping to take control back while praying they don’t do it again.

What’s ironic is that Meta pitched these AI systems as a way to prevent account issues and hacking.

In this March announcement, they said the support assistant was a way to "resolve account problems for you from start to finish" and said that its AI could "prevent an account takeover by noticing it was suddenly accessed from a new location, the password was changed, and edits were made to the profile." That's almost move-for-move what the attacks did.

One Meta AI was supposedly watching for exactly this, but a different Meta AI waved it through.

It looks like Meta has patched the issue, but it was active for months, with Telegram groups offering stolen accounts on the black market.

Who needs Mythos when you can just ask the Meta assistant to hack for you? 😅

Google Wants to Release 64 Million Mosquitoes Carrying Wolbachia Bacteria in Florida and California 🦟🦠

Back in Edition #457, I wrote:

Personally, I’m in favor of heavy mosquito control anywhere humans are present in any concentration. Mosquitoes can have the rest of the world — the planet is plenty big for everyone — but they’ve been annoying me for too long…

Alternatively, I’d take a shoulder-mounted automated laser mini-turret that shoots down any mosquitoes in a 30 feet radius 🤔

No luck yet on the laser turret, but it looks like Google’s Project Debug is working on this.

The plan reads like a Bond villain's opening monologue: release 32 million mosquitoes into California and Florida per year for two years.

BUT

This is the anti-villain plan. The goal is fewer infections and, if it works, fewer of the little vampires ruining your evenings outside.

The CDC calls mosquitoes the deadliest animal on Earth, and the one Debug is targeting this round is Culex quinquefasciatus, the southern house mosquito behind West Nile virus and St. Louis encephalitis. West Nile is the most common mosquito-borne illness in the US, with 1,300-plus severe cases and over a hundred deaths in a typical year. (Worth noting: Debug started by attacking Aedes aegypti, the Zika and dengue mosquito. This proposal is a pivot to a different 🧛‍♂️.)

The method is older than it sounds, and it works because of one biological quirk: male mosquitoes don't bite. Only females need a blood meal to make eggs, so releasing males adds zero bites to your summer.

Debug raises males carrying Wolbachia, a bacterium found naturally in loads of insects, and when one of those males mates with a wild female that lacks the same strain, her eggs never hatch. Repeat at scale and each generation comes out smaller than the last.

No genetic engineering required. Google didn’t invent Wolbachia. It, uh, borrowed it. This is the Sterile Insect Technique, a 1950s idea that already cleared screwworms and fruit flies off the board. Mosquitoes were just too delicate to mass-produce until the robots showed up.

And that's the part that makes this a tech story rather than a bug story. You cannot release the females (they bite, and they'd grow the population you're trying to shrink), so the whole thing rises or falls on sorting males from females accurately, tens of millions of times, cheaply. That used to be slow manual work; Debug built sensors, computer vision, and automated rearing to do it at industrial scale, which is the actual hard part.

One catch worth flagging: it's self-limiting. The released males die, nothing propagates through the wild gene pool, and the population drifts back unless you keep releasing. Reassuring if you worry about irreversible meddling, less so if you wanted one-and-done.

It's maintenance, not a cure: stop releasing, and they come back.

Does it actually work?

The Fresno field trials knocked biting females down 68% the first year, then 95%-plus, with the most isolated neighborhood hitting 99%. And in February, a randomized trial in Singapore covering 700,000-plus people found Wolbachia releases cut symptomatic dengue by more than 70% (published in the NEJM). Debug says it's now released over a billion mosquitoes across four continents.

If you're on team fewer mosquitoes, the EPA's taking public comments until June 5. 📩

(The main objection is ecological: collapse a population and you may affect the birds, bats, and dragonflies that eat them. My guess: real in general, overstated here, since both target species are invasive in North America to begin with, anything that eats mosquitoes also eats a lot of other (juicier) insects, and the Earth is a really big place. There will be plenty of mosquitoes left even if we treat near human population centers.)

🔊 Eddie Kramer on Hendrix, Zeppelin, the Beatles, and the Happy Accidents in the Studio 🎤🥁🎸

I didn’t even know who Eddie Kramer was before I watched this interview, but I enjoyed it enough to share with you. His anecdotes from the studio with Hendrix, Zeppelin, and even the Beatles a few times were super interesting.

He made me notice the glockenspiel on Little Wing in a totally new way. Apparently, Hendrix saw it lying around the studio, had never played it before, and added those well-placed notes to the song in a way that totally transformed its texture. He also has some anecdotes on Jimi’s cover of All Along the Watchtower.

The anecdote about the “woman” pre-echo on Whole Lotta Love is crazy. Zeppelin fans spent the 1970s lying on their beds with headphones, so they’ve noticed that during the middle part, the echo follows Robert Plant’s vocals on every word except one, where the ‘echo’ comes first.

Here, lemme pinpoint the moment using the timestamp feature (it’s quiet, so you may have to crank it up to hear):

It sounds almost supernatural, and people had theories that it was done with studio trickery. But Kramer says it’s accidental. A past take’s vocal recorded on another channel on the same tape bled through while they were recording, and landed in just the right spot! What are the odds of that?

Anyway, it’s a fun one. I just like these stories that tell us a bit of what it must’ve been like on the inside as some of these great records were being made.

🚨 If you haven’t read the book or seen the film, bookmark this and come back. Seriously. This one’s worth avoiding spoilers and going in blind. 🚨

We go deep on the book first, because it’s the foundation and the more complete version of the story, then turn to the film, the production, and what the adaptation gained and lost.

Some of the rabbit holes we go down: 🕳️🐇

• Not a reluctant hero. An avoidant one, which is very rare!

• Why making Grace alone on the ship is the decision that makes everything else possible, and how a group of humans may have reacted differently to first contact.

• Stratt runs one algorithm on every choice, and it’s the one most of us are too squeamish to run. Why she’s the best character in the book, and why the film’s karaoke scene is its worst mistake.

• The most alien alien possible: no face, lives in ammonia, looks like a spider. Weir stacked the deck against Rocky on purpose. So why do we love him? 🕷️👽

• Is Rocky a preview of humanity's first contact with AI? 🤔

• The one plot change in the film that Andy Weir says he wishes he’d thought of for the book.

• A species that never looked up, and what that says about everything humans built because we happened to see the stars. 🔭

• “Everybody did their job” on the film. The imperfectionist cinematography of Greig Fraser. 🎞️ 🎥

• Gosling carrying a whole film alone in a room with a puppet, a four-hour cut you’ll never see, and why the book is still the canon.

And, as always, we wander: Interstellar’s water-planet plot hole (Tinkered’s blood boils), whether more gravity would actually make Grace stronger rather than older, R2-D2 as the secret hero of Star Wars, the James Joyce theory of the “kneecapped” modern male, and me-burgers. 🍔

🧍⌨️🖥️ I wanted to show you my standing desk, so I took a photo and had AI redraw it (to anonymize it). And yes, I’m standing as I’m typing this.

Years ago, I read about the benefits of standing desks and figured I’d try.

My prototype was simply stacking a bunch of boxes on my desk to raise my monitor and keyboard to standing height. I tried a few days and liked it, so I bought a used IKEA Fredrik desk for $30. Some online forums recommended it as a cheap way to go standing.

The desk wasn’t designed to be standing, but because it had those top shelves and side posts with holes every few inches, you could mount the desk surface to standing height.

I used that as my main desk for a few years and got used to standing while working, and walking around the office as soon as I had something to think about. But then in 2014, my wife and I had our first kid, and oh boy, he didn’t sleep very well for 18 months.

Survival mode. I went back to a sitting desk 🥱

That situation got better… then we had our second boy, and he had the same sleeping genes. So I didn’t go back to standing, and inertia being what it is, I’ve been sitting ever since.

But during that decade, standing desks got WAY more popular. Many motorized models came on the market, and I started thinking about going back, but this time with a hybrid that could do both.

I bought a motorized frame from MotionGrey (on sale around $300CAD), and I asked a friend who’s great at woodworking if he could make me a hardwood top (👋 Fred! Thanks again 💚 🥃). He suggested a few possibilities, and we ended up going with white oak (it’s beautiful).

I’ve not been using it for that long (my wife can attest to how slow I’ve been to assemble it, even after the frame and top arrived). But I have to say: It’s a real quality-of-life improvement.

Without having to force myself, I end up working standing up at least 2-3 hours per day on average, and over the years and decades, I think that will add up to all kinds of benefits.

If you spend your day at a desk and haven’t got a standing desk yet, I recommend it. And if you have young kids, get a motorized one. Fixed-height is a commitment you may come to regret at stupid o'clock.

🏭🤖 Nvidia Q1 Highlights: Compute Is Revenue, Demand Goes Parabolic, and Jensen Wants the CPU Market Too 😎

Humans get used to things really quickly. I was watching Apollo 13 with my family last weekend (🚀🧑‍🚀🧑‍🚀🧑‍🚀). One of the plot points is that Apollo 11 (first time on the moon) had the whole world watching, but by Apollo 13, going to the moon had become seemingly so routine to most people that the major TV networks didn’t even bother carrying the crew's live broadcast. 😅

Sometimes it feels like this with Nvidia.

They have some of the best quarters any public company has ever had, and everybody goes 🥱 and takes it all for granted. I don’t necessarily mean that the stock should have moved more, because that’s the expectations game (yes, they beat “consensus”, but in the Keynesian beauty contest, beating consensus is itself the consensus, so it’s not really a beat 🔁). Mr. Market is clearly skeptical of the duration of growth (🤨).

But we’ve become blasé about these numbers very quickly.

• 85% revenue growth at that scale, selling physical products!

Jensen described it this way: “This was an extraordinary quarter, demand has gone parabolic.”

For comparison, the last time Google grew revenues at that pace was in Q4 of 2005. But at the time, its market cap was $120bn, not $5.2 trillion.

And Google’s gross margin back then was ~60%. That’s a purely digital business (at the time), vs Nvidia’s 75% gross margins, and they ship metal.

• Nvidia’s net income was $58.3bn in Q1, up 211% year-on-year 🤯 (GAAP, which includes $15.9bn of gains from equity securities, to be fair)

For most of its 33-year history, Nvidia was a gaming company. Now it doesn’t even report gaming separately. 🎮

They lumped everything that isn’t “Data Center” into “Edge Computing”, and all of it added up to $6.4bn last quarter compared to $75.2bn for DC. One big downside of that, IMO, is that networking isn’t broken out as a segment anymore. It’s now part of DC, which is too bad, though we did get specifics in the CFO commentary:

• “Networking revenue was a record $14.8 billion, up 199% from a year ago and up 35% sequentially.” 🛜

Let’s dive into management’s commentary to see what’s going on underneath those numbers:

One thing they try to do is convince the market that they’re not only selling to a handful of hyperscalers. They will report two segments within DC, with the hyperscalers on one side, and what they call ACIE on the other (AI Clouds, Industrial, Enterprise, which also bundles in sovereign, on-prem, and any odds and ends):

Colette Kress (CFO): Hyperscale revenue of $38 billion was approximately 50% of Data Center revenue and increased 12% quarter-over-quarter.

ACIE revenue was $37 billion and grew 31% quarter-over-quarter, including AI cloud revenue that more than tripled year-over-year. Our customers have enabled rapid stand-up of AI compute capacity.

The number of partner data centers exceeding 10 megawatts has nearly doubled in just 1 year, now surpassing 80 sites.

Sovereign revenue increased more than 80% year-over-year.

Hyperscale grew 115% YoY, faster than ACIE's 74%. Doesn’t quite fit the "hyperscaler AI spend is maturing" narrative. In fact, hyperscalers are accelerating faster than the new diversified base Nvidia is trying to highlight.

Kress also made a pitch against the 'Nvidia is more expensive' refrain:

Today’s data centers are revenue-generating AI factories […] Customers do not buy GPUs. They build AI factories and the right economic metric is not the purchase price of the GPU. It is the lifetime cost of an AI factory producing intelligence, token per watt, tokens per dollar, uptime, utilization, time to production, software durability and asset life.

Constrained by power and capital, AI factory operators must choose the right architecture. With our extreme codesign approach, we deliver the industry’s lowest token cost, the highest token throughput and the highest ROI. MLPerf Inference results are in, and once again, we swept every benchmark as Blackwell Ultra delivered the highest throughput across the broad set of models and deployment scenarios.

Full stack innovations drove the 2.7x increase in throughput and a 60% reduction in the cost per token on GB300 compared to just 6 months ago.

That's the moat many people miss. Even if you catch up to last quarter's Blackwell, this quarter's Blackwell is 2.7x faster on the same chips. Software optimizations ftw.

They also announced a “deepened” partnership with Anthropic, but I'm unclear what that actually means. I’m guessing they sweetened their offers to them to pull them away from TPUs and Trainiums a bit ¯\_(ツ)_/¯

After years of GPUs getting all the love, CPUs are back in the spotlight, and Nvidia wants its big slice of the 5-layer cake (🍰) there too:

Colette Kress: Agentic AI and reinforcement learning represents new growth opportunities for CPUs. Building on the success of our Grace CPU, Vera is arriving just in time to meet this inflection. Built on custom ARM cores and codesigned end-to-end with Rubin GPUs and NVLink, Vera will deliver up to 1.5x faster performance per core, 2x performance per watt and 4x density per rack compared to x86-based alternatives.

Vera CPU opens a brand-new $200 billion TAM for NVIDIA, a market we have never addressed before, and every major hyperscale and system maker is partnering with us to get it deployed.

I’m always wary of large TAM numbers, but in the AI world, big numbers have had a tendency to materialize.

We have visibility to nearly $20 billion in total CPU revenue this year, setting us up to become the world’s leading CPU supplier.

More from Jensen on why demand for CPU is exploding:

Jensen: Claude Code is essentially a harness around Claude. OpenAI's Codex is a harness around the GPT-5.5 model… these harnesses provide for things like I/O, orchestration, memory management, tool use connected to tools, for example, browsers and things like that, C compilers, python compilers.

the harness runs on CPU. And the tool use runs on CPUs. So for example, if the AI were to do a search or do a browser, use a browser, that would run on the CPU. The world has 1 billion users, human users. My sense is that the world is going to have billions of agents.

Not today, I mean, we’re going to grow into it, but we’ll have billions of agents. And those billions of agents will all use tools. And those tools can be like PCs, just like us humans using PCs today.

Grace (which was bundled) and now Vera (which can be purchased standalone) allow Nvidia to sell the whole stack, rather than relying on AMD and Intel CPUs. They’ll still offer them, but it probably feels good not to have to sell your competitors’ products.

Morgan Stanley had an estimate of the impact of rising memory prices on Vera Rubin, Nvidia’s next generation:

Bonkers, no?

It'll be interesting how long they can keep passing on those COGS to customers without taking a margin hit. And whether less differentiated competitors get squeezed harder by the same memory inflation. 🗜️

On China, it’s still Schrödinger's market. 🇨🇳🐈

• Q1 FY26 had $4.6B in Data Center Hopper shipments to China.

• Q1 FY27: zero.

And they still grew 85% anyway.

They got approval from the U.S. side for H200, but got blocked from the Chinese side. For a while, they were blocked from the U.S. side but got demand from China. Who knows where this will go, but they say that they aren’t including any revenue from China in their forecasts.

Despite that, they're guiding $91bn next quarter, another sequential acceleration on top of a record base.

Finally, on the capital allocation front, since it doesn’t look like they’ll plough tens of billions into the frontier labs anymore (Jensen said the recent $30bn OpenAI check and $10bn Anthropic check are probably the last big ones, since they're heading toward IPOs), they announced an $80bn buyback authorization + raised the dividend from $0.01 to $0.25. Not moving the needle that much, but at their scale, options are limited.

They generated $48.6bn in free cash flow just last quarter. The question becomes: what do you do with it? 💰💰💰

🗣️💬 Gavin Baker: When Software Becomes Labor, TSMC as the Accidental Central Bank of AI, GPU Racks in Space, Etc

Interesting interview on the state of the markets and AI.

Here are highlights:

-The Vertical ARR Curve: AI Revenue Has Entered the Weird Zone 🛸

Gavin Baker: what [is] happening in AI was the most extraordinary moment in the history of capitalism, the history of American business. What I mean by that is Anthropic added $11 billion of ARR. What is astonishing to me about this, is the SaaS and cloud revolution created, we’ll call it, between $5 and $10 trillion of value. Arguably the 3 highest-profile SaaS companies in the last 10 to 12 years are Palantir, Snowflake, and Databricks. These 3 companies employ thousands of people, tens of thousands collectively. They’ve all spent 10 years building their businesses, and Anthropic added their combined businesses in 1 month.

Nothing like that has ever happened in the history of capitalism — forget my career, just the flat-out history of capitalism, the history of business. It’s wild.

So what explains this? How can AI labs grow at a rate that would’ve sounded fake in almost any previous cycle?

I think it’s because software revenue used to be tethered to humans, even when the software itself scaled beautifully. I mean, it’s great that copying bits has zero marginal cost, but if to get more usage you need more employees, more seats, more workflows getting approved, more training, more integrations, more sales people and more steak dinners, more people changing their habits… there’s still a lot of friction in the system.

Or to put it another way: Even the best SaaS companies had to pass through the narrow straw of human adoption. 🥤

With AI agents, that straw turns into a firehose.

If you give a company 1,000 AI agents, you don’t need to hire 1,000 people before they can start consuming tokens. They can scale from 10 active tasks to 100,000 tasks overnight. Compute consumption can ramp up instantly by orders of magnitude without waiting for Debbie from HR to give orientation to a single person.

Software used to amplify labor. Now software is becoming a kind of labor.

This doesn’t mean that things won’t ultimately be limited by other factors, including ROI on all those tokens, which are increasingly expensive (and as I wrote in Tokens Schmokens, a bad metric).

-TSMC as the anti-bubble central banker 🐜🏗️🇹🇼🫧

Gavin Baker: I have been optimistic that this fundamental shortage of wafers, which today is controlled by Taiwan Semi, will prevent one. If Taiwan Semi did what Jensen wanted, I think Nvidia could sell $2 trillion of GPUs in '26 or '27, maybe $2.5 trillion, maybe $3 trillion. But there is a limit where consumers would consume so much, that you probably would be in an overbuild. So Taiwan Semi — if we don't get a bubble, we need to throw a party for them, because they will have single-handedly prevented a bubble.

Usually when people ask “is AI a bubble?”, they look at demand: hype, valuations, capex plans, extrapolated revenue, etc. 📈

What if the answer is on the supply side?

TSMC’s multi-year lead times and conservative capital expenditure are acting as a hard ceiling on global wafer output. Even if you have the cash, you can’t overbuild, or at least, not as much as if supply was freer.

It’s almost like TSMC is the accidental central bank of AI, and they have a “wafer monetary policy” trying to keep the AI economy from running too hot. 🏦

What will be a secondary effect of this?

Forced Capital Efficiency: Because hyperscalers cannot buy all the raw compute they want, they are being forced to innovate at the algorithmic and optimization layers much earlier in the cycle than they normally would.

Kind of similar to what is likely to happen because of memory supply constraints. Expect optimizations to come that will reduce memory usage, possibly significantly (it’s impossible to predict breakthroughs, but we can look at incentives and know that they have changed A LOT in recent times, and the Eye of Sauron has turned to RAM 👁️).

-When Junk Companies Become Cash Machines 🗑️➡️💰

Gavin Baker: Because we are in shortages, the lowest-quality companies are doing the best. If you’re an oil and gas investor, a mining investor, natural resources investor, and you’re well-versed in thinking of costs, this is very intuitive to you. In a real bull market for a commodity, the commodity suppliers with the highest costs go up the most because it’s the most beneficial to them. They go from on the verge of bankruptcy to gushing cash. This is one reason commodity investing is really, really hard. Because quality outperforms during the cycles, but you get all of the outperformance during the downturns when the high-cost guys who mooned during the shortages and the commodity bull markets go bankrupt or whatever.

You’re seeing that happen in every industry. The lowest-quality players — companies that are hated and detested by the hyperscalers and the buyers because they have high costs, they’re unreliable, the parts fail at a high rate — they’re sold out and raising prices. And then that activity gets the interest of these retail accounts on X, and these stocks get bid to the moon. Whereas some of the higher-quality expressions have actually really underperformed. As an investor, it’s hard because you know within a shadow of a doubt that the thing that’s mooned 10x in 3 months or 6 months is going to go right back down, subject to what they do with all the cash.

That can be counterintuitive if you’re used to thinking “better business = better stock.”

Anyone who has looked at levered equity stubs with high risk of bankruptcy knows that operating leverage cuts both ways. And when the direction of travel reverses rapidly, the results can be pretty crazy. 🚀

🗣️💬 Anthropic’s CFO Krishna Rao: Compute is our lifeblood 🩸

I rarely feature two interviews by the same interviewer at the same time, but Patrick was on a roll recently and I enjoyed both enough to highlight.

There’s more interesting stuff in this one than I can fit here, so I recommend that you listen to the whole thing to get a better idea of how one of the most consequential companies operates and thinks internally.

Oh, and maybe it’s just me, but it’s a little weird to listen to the audio version because Krishna’s voice has a timbre that sounds a little like Patrick’s (at least, it does at 2x).

Here are my highlights:

-Compute Allocation > Capital Allocation 🤖🤖🤖

Krishna Rao: The compute that we procure is the lifeblood of our business.

It is the most important thing in the company. It’s the canvas on which everything else gets built. The decisions we make on how much compute to buy are some of the most consequential and hardest decisions to make in the entire company. [...]

Thinking of it as not just something that is a variable cost over some time period, but really this resource that’s so fungibly utilized. We run workloads on one day in the morning on a chip for inference, and in the afternoon or evening, we use it for model development.

That paradigm does not exist in a company like a software company or a factory. You can’t repurpose — if you have a bunch of people doing R&D and that’s your R&D expense, they can’t go and become COGS, and vice versa, in most traditional companies. Here, you really have that fungibility. That’s possible.

That’s where the return on compute is so important, and I think people are beginning to understand that. But there’s still a tendency towards treating it like, “Oh, I have to separate these two costs,” when in actuality they’re very self-reinforcing, and that flexibility is what helps to drive revenue short term and long term.

He also drops a crazy stat:

“Our net dollar retention rate is over 500% on an annualized basis.” 🫡

Elite SaaS sits at maybe ~130%. Some exceptional ones have been at ~150-170%.

500% is unprecedented.

And then this:

“On the way here, I was in an Uber, and I signed two double-digit million-dollar commits in the car ride, which was 20 minutes.”

Reminds me of the anecdote about how in eBay’s early days, one guy’s job was just to open envelopes full of checks. This is the AI-era equivalent 😅

-Frontier models unlock TAM, not just better benchmarks 🔓🔑

Krishna Rao: Every time we have a new model, there’s a set of capabilities that are different. People tend to think about model intelligence as IQ — a single number. “Okay, this model was at 110, and then it goes to 125.”

We think of it differently.

Intelligence for us is multidimensional. It’s not just a score. We find that, yes, everyone publishes their model benchmark cards. We find that a lot of those benchmarks are saturated. We publish it too, but our measurement is what the customers tell us. What is the real-world capability of this model?

As we’ve released better and better models, what we’ve seen is it’s not just the outright intelligence. It’s also the ability to do long-horizon tasks. It’s the ability to use tools, or computer use. It’s the ability to do agentic tasks that have specific value even faster. […]

What we’ve found very consistently is that by releasing new models, the TAM is unlocked in a unique way. More TAM gets unlocked. More use cases are possible.

A good illustration of that is this last four months that we’ve had at the company. We started the year with about $9 billion of run-rate revenue, and we ended the quarter with north of $30 billion of run-rate revenue. That kind of a change is enabled by these model intelligence leaps, and then the products that we build around them. That’s what I mean by the returns to frontier intelligence are really high.

I think that’s an important reframing.

It may not seem like a big deal at first, but going from “same thing but better” → “new use cases, new possibilities” matters if we want to understand what is likely to keep happening.

A better model doesn’t just take share inside the existing market. It can colonize whole new corners of the economy.

And what’s 🤯 is that just by the time this interview was recorded, edited, and came out, Anthropic’s run-rate went from $30bn to roughly $45bn, based on the latest reporting.

In fact, there are reports in the WSJ that Q2 is predicted to show $10.9bn in sales, up from $4.8bn in Q1, as well as their first operating profit ($559M). But Anthropic isn't guiding to sustained profitability, they expect to keep losing money for a while longer as compute spend ramps. It’s almost an accidental profit ¯\_(ツ)_/¯

-Anthropic’s Escher Hands Moment 🔁🪞🤖 ⌨️

I wrote about the Escher Hands Era, and clearly we’re going deeper and deeper into it:

Krishna Rao: I can’t speak for other companies, but for us, the scaling laws are alive and well, and we’re seeing that with releases more recently like Mythos. But right now, within the company, 90-plus percent of our code is actually written by Claude Code. A lot of Claude Code’s code is written by Claude Code.

Why do we allocate compute internally? Why would we forgo revenue for it? It’s because the models themselves are helping us build that next generation of models.

Clearly they’re not building with Sonnet.

It’s obviously Mythos that is coding the next version of Claude, and the fact that they haven’t released it widely (which means it can’t be distilled or studied by competitors) probably also has to do with extending that recursive advantage for a bit longer (not just cybersecurity and compute constraints).

There’s also good stuff on how they think about compute allocation, how fungible it is between different use cases, and how they are the only lab more or less agnostic between using Nvidia/TPU/Trainiums.

🧪🔬 Liberty Labs 🧬 🔭

🐜 From Six Dells to 4,032 x GB300s: Inside Jane Street’s New Datacenter 🛜

Caveat: Jane Street is a Dwarkesh sponsor and produced this video. It’s marketing, so treat it accordingly (🧂). With that said, it’s fun to get a tour of one of their datacenters.

It’s a recent one in Texas that they use for training AI models, running liquid-cooled Nvidia GB300s (!). They talk about how much work went into making the DC liquid-cooled, and how many sensors and failsafes they have to detect and isolate leaks (you don’t want to short out millions of dollars of equipment because of a leaky pipe!).

Compared to what hyperscalers are building, this is a tiny cluster, but even with just 4k GPUs, there’s over 8,000km of fiber in that deployment (the distance from Lo Angeles to Tokyo)!

After the DC tour, they sat down to discuss some of the stuff JS does:

This part is 🤯:

There are trading systems we build, and trades that we do, where in order to be competitive you actually have to turn around a packet in under 100 nanoseconds.

That’s a very different regime, right?

People sometimes ask, “Can you write high-performance stuff in OCaml?”

And the answer is: we can. But for this kind of speed, it doesn’t matter whether you write in OCaml, Rust, or C++. You can’t use a CPU.

You’re going to be on an FPGA that’s directly attached to the network, and you’re going to be turning around the packet so fast that if you attached an oscilloscope to the wire on the way in and the wire on the way out, you would see the packet start to leave before it’s done being consumed.

So it’s a very different, very specialized regime. And when you’re in that time regime, you really can’t do very much computation.

This made me curious how much throughput came from the raw feeds from the various exchanges (equities, options, FX, crypto). This is what I found with the help of both Claude and GPT-5.5 (with multiple rounds of them fact-checking each other in extended thinking mode, but errors can remain):

Man, Options are not just bigger than equities… they're in a different weight class. ⛰️

Nasdaq's April 2025 systems commentary has a useful reference point: roughly 165 billion options messages per day versus 7 billion equities messages per day on its systems. A ratio of about 24:1.

So the guesstimate (because this isn’t public info) is that for a tier-1 multi-asset firm like Jane Street, total provisioned inbound market-data capacity is in the hundreds of Gbps range.

And then what kind of compute do you apply to all this raw data... That’s another question entirely.

Cloudflare’s Experience Hunting Security Flaws with Mythos 🔐 🏴‍☠️

It’s starting to feel like Mythos is building a separate brand from “Claude.” The longer Anthropic keeps it unreleased and separate, the more it’ll feel like its own thing 🤔

Anyway, back to the cybersecurity beat, Cloudflare shared its experience using it:

We soon pointed [Mythos] at more than fifty of our own repositories – to see what it would find, and to see how it works. [...]

Mythos Preview is a real step forward, and it’s worth saying that plainly before getting into anything else. We’ve been running models against our code for a while now, and the jump from what was possible with previous general-purpose frontier models to what Mythos Preview does today is not just a refinement of what came before.

It’s a different kind of tool doing a different kind of work, and that makes a clean apples-to-apples comparison to earlier models difficult.

Mythos isn’t just acting like a better static analyzer. Cloudflare says the big leap is in exploit-chain construction and proof generation.

In other words, it can find several individually unimpressive bugs, reason about how they combine into something more dangerous, then write and run proof-of-concept code to test whether the exploit actually works. 😬

And even if you can use tools like Mythos to find vulnerabilities faster, and then fix your code faster, if the rest of the pipeline for deployment remains the same, it won’t be able to handle this new work. Cloudflare explains:

The loudest reaction to Mythos Preview from other security leaders has been about speed - scan faster, patch faster, compress the response cycle. More than one team we have spoken with is now operating under a two-hour SLA from CVE release to patch in production. The instinct is understandable: when the attacker timeline shortens, the defender timeline has to shorten with it.

Faster is not going to be enough, and we think a lot of teams are about to spend a lot of time, effort, and money learning that the hard way.

Patching faster does not change the shape of the pipeline that produces the patch. If regression testing takes a day, you cannot get to a two-hour SLA without skipping it, and the bugs you ship when you skip regression testing tend to be worse than the bugs you were trying to patch.

🎧🇺🇦 Ukraine: Update from the Frontline of the Drone Wars

The latest episode of WarTalk has guest Rob Lee reporting from Kyiv on how things are these days in Ukraine. Drone tactics, how both sides are organizing operations, what's likely next, and why Rob Lee thinks Starlink is the game-changer of this war.

The part about how Vampire drones are used for logistics is very sci-fi. They airdrop medical kits to wounded soldiers, lay mines, and carry infantry packs so the guys can sprint all out across open ground until they reach cover, where the drones drop their gear off, like flying sherpas.

Rob Lee also says that only about 2% of Ukrainian casualties in one area came from small arms. The 'forward line of troops' has been quietly replaced by a forward line of drone teams.

🧠📊 The Two-Thirds Decline in Dementia Risk, and Why Cases Keep Climbing

We still need to figure out how to bend that curve down, but at least we can clearly see some progress over the decades.

The good news first:

A comprehensive analysis of three large population-based studies found that the age-adjusted prevalence of dementia has decreased by two-thirds over the past 40 years (Stallard et al., 2025). The data revealed a staggering 67% drop in dementia risk at any given age over this period.

For instance, in 1984, 30% of people aged 85–89 had dementia; by 2024, this figure had fallen to just 10%. Additional analysis of the data also revealed that each successive five-year birth cohort has a lower risk of dementia at a given age than did their predecessor.

But still:

Dementia is one of the biggest healthcare challenges of the 21st century, affecting millions worldwide. In the UK, nearly 1 million people are currently living with dementia, a figure projected to rise to 1.4 million by 2040. In the United States, more than 6 million people suffer from dementia, and the condition is responsible for over 100,000 deaths annually.

Dementia also carries a substantial economic burden, with total costs exceeding $600 billion annually in the United States. (Source)

Despite the encouraging decline in dementia incidence, the absolute number of people living with dementia continues to grow because the average age of the population keeps going up (as fertility keeps going down).

🚀🔧🌕🧑‍🚀🧑‍🚀🧑‍🚀 Apollo 13: The Hard Way Ages Best 🌎

Rewatched this with the family last weekend. First time in years for me, first time ever for my two kids. It was even better than I remembered. Probably my favorite Ron Howard film.

About halfway through, one of my kids asked “Wait, all this happened?”

Yep, pretty much. They worked really hard to keep it accurate.

The zero-g still looks amazing.

This is a 1995 film, so the effects should look dated. They don’t, because Ron Howard refused to fake it with wires. He talked NASA into letting them use the KC-135 reduced-gravity training plane (affectionately known as the “Vomit Comet” 😅). It flies parabolic arcs that produce about 25 seconds of free fall at a time.

The eleven-person cast and crew flew 13 days over a four-week period, did 612 parabolas, all that to get probably no more than 15-20 minutes of usable zero-g footage that ended up in the film.

Kevin Bacon described it: 40 parabolas in the morning, lunch (which someone, foolishly, decided should include Mexican food 🌮🌯), 40 more in the afternoon. 🤢

There’s a reason other sci-fi productions don’t do this! You have to be a little crazy.

My kids never even questioned it. They just took it as given that they were watching people in space.

A few other things that made me appreciate it more this time:

• It’s a systems movie, not an action movie. The hero isn’t a person, it’s a process: checklists, communication loops, simulations, redundancies, inventory. Everyone solving small problems in the right order. The heroes are not saved by one genius epiphany. It’s dozens of small correct decisions made under pressure.

• The CO₂ filter scene (make this square thing fit into that round hole) is probably the nerd ideal of constraint-driven engineering on film. 🤓🛠️

• Both famous lines are slightly off from the historical record.

  • Jack Swigert actually said “Okay, Houston, we’ve had a problem here.” Past tense. The film changes it to present tense (”Houston, we have a problem”) because it’s punchier.

  • “Failure is not an option” was invented for the screenplay. The real Gene Kranz never said it. The line stuck because it captures the culture perfectly, which is what the movie is faithful to, even when it isn’t transcript-perfect (but a lot of the other dialogue comes fromt recordings and transcripts).

• A sadder note: Jim Lovell, the real commander whose book the film is based on, died in August 2025 at 97. He has a cameo near the end as the captain of the USS Iwo Jima, the recovery ship. Ron Howard apparently wanted him to play an admiral, but Lovell said: “I retired as a Captain; a Captain I will be.” 🫡

If you have kids who haven’t seen it, this is a great family watch. Suspenseful, clean, historically rooted, full of adults behaving like adults under pressure… which is rarer than people admit.

Unthinking respect for authority is the greatest enemy of truth.

—Albert Einstein

🌖↔🌎 I think most people know about ocean tides, even if few people understand all the variables that make them so complex to accurately predict (it’s not what I want to get into today, but it’s an interesting phenomenon).

But there’s another kind of tide that I didn’t know about until recently:

Solid-Earth tide!

Yep, gravity doesn’t care if you’re a liquid or a solid. It pulls, and over something as large as the Earth, you get an actual tide in the crust too (which is why they also call it crustal tide, but that sounds a lot yuckier).

The ground under your feet can rise and fall by several inches (tens of centimeters) over a tidal cycle. You don’t notice it because everything is moving very slowly with it (buildings, roads, whole cities). It’s probably happening right under you right now!

Earth tides, like ocean tides, vary a lot based on latitude, local geology, and the lunar/solar alignment.

This has to be taken into account if you want very precise spatial positioning. The International Association of Geodesy (I had never heard of it before) says: “The entire planet’s surface rises and falls by up to about 30–40 centimeters twice daily. This deformation affects geodetic reference frames, satellite orbits, and precise positioning, requiring continuous modeling and correction in space geodesy.” 🛰️

One of the things that didn’t make immediate sense to me about tides (water or crust) is that there isn’t just a bulge in the direction of the moon. There’s also a bulge on the other side. 🫤

What unlocked my understanding was when I learned that tides are caused by differences in gravity across Earth, not just the direction of gravity.

So imagine three cars driving at the same speed in a line: 🚙 🚙 🚙

If the front one accelerates a lot, the middle car accelerates moderately, and the back car only accelerates a little (gravity pulls more strongly on what is closest than what is farther away), then from the point of view of the middle car, it looks like the line has stretched in both directions.

That’s the two-sided tidal bulge.

Wait, why am I writing about Earth Tides? I guess we don’t always pick the rabbit holes we fall in! 😅

✨ Constellation Software’s ✨ 2026 Annual Meeting

First, I gotta say, I’m a little disappointed in myself. After years of wishing they would go back to an in-person meeting, they finally do, and I wasn’t there. I didn’t have a huge scheduling conflict or anything, I dithered a little too much, time flew, and the date snuck up on me and it was kind of too late (well, I was also really busy with lots of projects and family stuff, but when is that not the case?).

So I didn’t get a chance to see my old friends in person, or to make new ones. Next year!

The meeting was over 4 hours long, but friend-of-the-show Trevor Scott (🍁) made this supercut (👆), condensing it into 36 minutes. That’s a good way to get some highlights.

Here are mine.

First, like everything else in the world of technology, AI was a huge focus. It’s both what shareholders are uncertain about AND the main technological driver of change these days, so it’s everywhere.

As a sentiment check, they were in a good enough mood to make a joke about changing the name of the company:

Speaking of culture, Mark Miller followed in Mark Leonard’s footsteps and has elected not to receive a salary or bonus as President (Constellation doesn’t have a CEO). Leonard had stopped taking a salary in 2014, and in 2015, he also decided to drop other bonuses and incentives too.

Mark Miller: Yes. I just carried on what Mark Leonard did. And I really care a lot about this company, and I took this job to help this company and the shareholders in it.

John Billowits: Mark wanted 0 comp, and we wanted to pay him something.

Something stood out to me at this AGM. Not with huge certainty, but I moved my thinking in that direction a bit: CSU's weird structure may be unusually well-suited for this moment, at least compared to most other software companies.

Decentralization plus running lots of experiments and scaling up what works is how markets work. With 1,500+ small units that can each experiment close to customers and share what works with the rest, interesting ‘invisible hand’ effects are emerging.

AI Case Study: When 50x Faster Changes the Question 💡

David Wilkes: I experienced one of the Volaris AI workshops back in March last year. And I went away from that with one question, which was simply how fast can we go. And what I did on day 1 was I stopped all development across both businesses.

So [at] CELCAT and Bullet [we] stopped for the whole month of April last year, and went on an intensive learning program, to learn what we could do with the technology. And I think if I look back and then we look now at the outcome of that, it’s actually pretty straightforward.

I like this idea of taking an actual pause to really focus on learning. Too many try to learn complex new workflows and tools on the side while doing things in the old way, and that’s rarely very effective, or at least, it isn’t for everyone in the org (some nerds will always race ahead).

At the outset, we came back in May, and we were going faster. If you think of a cycle time from concept through to production software, typically for us, that was measured in months. When we came back in May, we already started measuring that in weeks. And as we went through last year, we turned that from weeks into days. And today, our cycle time is measured in hours.

We can cycle from concept through to production in hours. And that means a road map that might have taken, say, a whole year […] that can be literally a week now.

So this pace at which we produce software is no longer a problem that we have different challenges instead. But it’s fundamentally transformational in terms of what it means for our business.

Jeff Bender: And how are your customers reacting to this? Can you talk to that?

David Wilkes: Yes, yes. Well, let me put that first in the context of growth. So if I go back to the end of last year, our growth was running at about 12% per annum. To date, it’s running at 23% per annum. Our vision is that we’ll double our revenues by 2029.

I think I’ve also been told I’m sandbagging on that. The interesting thing there is that growth. It’s not driven by going faster. It’s driven by us asking a totally different question, and that is, if we can go 50x faster than what does that look like for our customers. So what does 50x faster look like for our customers?

Speed can go from quantitative to qualitative if there’s a big enough change in velocity. You don’t just do the same thing faster, you do whole different things, you do more and create new value.

That's exactly what you'd predict in a Jevons-paradox-of-software world. Nice to see it confirmed by an operator.

And for us, that meant we’ve literally rebuilt our product from scratch. We’ve, in effect, reimagined what a new category of product might be. If you think about our old product, it was a system of record. You created, read, updated, deleted data. Our new product is a system of action.

It thinks, it predicts, it gives you insights. It does really clever stuff for you. So that creates a huge value for our customers and with value comes new price points doesn’t it? And with that, we are driving growth, and we’re seeing the results of that already.

If development goes from months to hours, the roadmap stops being a fixed annual plan and becomes more like a live conversation with customers. Ideas that used to be too small, too weird, or too low-ROI to justify engineering time can suddenly become worth trying.

"System of record" → "System of action"

Agents Need Managers & Names (and Slack Accounts) 🏷️

Interesting anecdote about the use of AI agents, and how to integrate them in the human org:

Andrew Jones: Rather than having support agent #1 and support agent #2 and support agent #3, we decided to name them... we wanted to get adoption of the agent. [...]

They all have a Teams [chat] account. So rather than you having to go to some web page or try to find it, you Teams them. You communicate with them exactly as you would with anyone else within ClickDimensions. And I think that’s the most important thing. [...]

The other thing is as well is by giving the agents names, you also have a human who’s a manager of them, because again, this is really vital when you set up agents is. If you set up an agent and you leave it to its own devices, it will go off. And over a period of time, it will go on a tangent. You need to have a human manager who manages those agents all the time. So by giving them a name and managing it, that’s the way we move forward with it. [...]

It took us about 4 weeks to do it after going through those various steps. We launched it in January of 2026. And what we found was that with our customers’ interactions with this chat agent, conversational agent rather than being a lookup agent, it was a problem resolution agent.

It effectively resolved 82% of all our Tier 1 tickets that went through the chat agent, which is fantastic.

These agents may not be as good as talking to a human, but at a lot of companies, that’s not where you start anyway. Replacing more limited agents can help solve a lot of customer problems faster and free up human agents to deal with the more complex cases.

The AI Hackathon That Built Solutions Nobody Deployed 💾

I’ll leave you with this anecdote told by a shareholder:

Ashwin Annamalai: In Waterloo, there was a hackathon called Anhackathon that was organized for university students where they were like businesses come with their problems, use AI and solve our problems. Like this is amazing. So with the help of AI with Claude and all these tools, they should be able to solve all these problems. So you know what, they did manage to solve the problems. But at the end of it all, zero solutions were deployed for the business.

That’s when — it was the lightbulb moment for me. And I was like, yes, building code is one part of the solution, but having the ownership and the trust is really important. The very next day, like started buying Constellation.

Mark Miller’s response: Success is not judged on your ability to develop products. Success is judged on your ability to go out and convince the customers that they want to use your product.

Now, I don’t read too much into this because in reality, it’ll most likely be competitors that adopt AI and use it to compete better, and they’re likely to have a lot more existing customer relationships and sales knowledge than university students.

But it also means that as long as you don’t fall behind those competitors, it’s more of an arms race than bringing a knife to a gun fight. 🔪

🏎️ Innovation cycles vs procurement cycles 🐌

A good reminder that it’s not because you innovate fast that you can sell fast:

Bill Delaney at Modaxo: They’re asking us about the pace of change from an innovation perspective. And we looked at the research, and it was clear that innovation cycles were compressing right?

From months to weeks and soon to be days. And I looked around the room and I said, but what’s happening with procurement cycles.

Now we deal with large government procurements that have — it takes multiple years for a procurement even to come to tender, then they run the tender process, you do a multiyear project and then you have 10 years of maintenance. Those procurement cycles and government are getting even longer. So we’ve got this dichotomy of extended procurement cycles compressing innovation cycles.

Even if the tech is perfect, that's not what wins the deal:

Bill Delaney: The elements of those tenders that really people should have a look at there’s elements around product capability and functionality and — but then most of the scoring goes to your experience, your ability to contract on the heavy-duty terms that they’re putting forward — and they need somebody to take liability, right? Governments like to shift risk — so you have to have capacity to take liability that might be through accepting LDs if we don’t perform, posting bonds or guarantees. You’ve got to have a scale on our capacity to do that.

That’s a big advantage that incumbents have in public or highly regulated industries. A new entrant with a perfect product that they sell for 1/10th the cost may still struggle.

AI = Layoffs? ✂️

In response to a shareholder asking whether AI productivity gains will lead to layoffs:

Bill Delaney: I don’t see us doing large-scale layoffs. No, not at the moment. We’re so focused on how to leverage this capacity because what you want to understand is we just have an enormous backlog of our customers wanting us to do things for them. Some of those things that just didn’t make business sense now do make business sense.

On the backlog/organic opportunity:

Barry Symons (Jonas): I do the hypothetical, if the business gods came down from above and said, ‘Barry, here’s the deal for you. You will never ever, ever win another customer again in Jonas’ history. But at the same time, you will never ever, ever lose a customer that you currently have in the Jones organization. Would you take that deal?’ And I say 150%, I would take that deal because there’s so much more we can do for our customers. And AI just makes it so much easier.

But wait, why weren’t they doing all this before?

Time to trot out Jevons' paradox again.

Cheaper development reveals a giant backlog of work that wasn’t ROI-positive before (or at least, wasn’t a higher ROIC than other ways to spend the capital, such as M&A).

But are they seeing organic growth from this yet? 🤨

Mark Miller (President): I’d love to see more organic growth. I’d love it to be yesterday […] I also haven’t seen a lot of new revenues from AI as well. So we’re just being -- we’re just trying to drive adoption of the usage of it, and we’ll monitor it internally

Like most things, investment comes before return, so this isn't a surprise yet.

Jamal Baksh (CFO) on cost: It wasn’t a material increase in that COGS line that. yes, I would believe that, yes, we’re probably outpacing revenue with cost today because we’re investing a lot. But it’s not a material impact on margins.

Has AI caused any customer attrition yet? 💸

This was a recurring topic:

Mark Miller: We really haven’t seen any AI specific attrition at any point.

Jamal Baksh (CFO): I look at about 900 of the businesses and look at trending of organic growth... there are a couple of things that might have been popped out and both of them had nothing to do with AI.

Jeff Bender: There’s no specific evidence to date of any significant or material attrition as it relates to AI. But I do believe it’s coming... Stay paranoid right? Like always.

💰 On Capital allocation (the core competency) 💰

The biggest challenge for the company has long been to deploy its free cash at high ROIC, and most of that has been through M&A. This remains the core function:

Bernie Anzarouth (CIO): We had a slide up there earlier that said we had how much, $3 billion of dry powder. We're trying to invest that capital, and it's a very tough slog. It's tough despite the number of VMS businesses that are out there, it's tough to use to redeploy all of our capital. And that's why we came up with the idea of PEMS [...]

How’s the runway? How’s the runway? Everybody always asks about the runway… Bernie doesn’t seem worried:

Our database of these software companies is still quite large, and it's still building.

I’m trying to remember the last number I heard. I think it was ~60k VMS that they were tracking. Probably way more now, my number is dated.

Bernie: And if you think of what the software world is all about, especially now with AI tools that are out there that you can get more software businesses that are created on a regular basis, the number of acquisition targets that are here today will be multiplied several fold over the next 10 years or so.

On the investments in public companies (PEMS):

Bernie Anzarouth (CIO): If you think of the way that we've done acquisitions to date, we buy businesses lock, stock and barrel, and it takes 1, 2, sometimes 3 years to get them up to speed with the best practices that we use to run our businesses. And so if you think of a minority shareholder and how much influence you can have on a business that you do not own 100%, it will obviously take a little while longer in order to influence management to do the right thing. And so what we believe is that we have to get them at a lower price than the businesses that we are actually acquiring at 100%. And so you will see if we measure ourselves at the same IRR that we measure 100% ownership, we would have to get these businesses at a lower price.

Sounds like it’s currently possible to get that extra discount because publicly traded software has been hit a lot harder than the private market. But maybe it’s just a lag, and private acquisitions will get more attractive… which may make PEMS less so.

Billowits had a good line:

We do believe that we want to have the opportunity to take advantage of which could be a dislocation in the market for a period of time. So keep selling vertical market software businesses. We want valuations depressed as long as possible.

🫡

Mark Miller (President): 25 years ago, we — we used to buy minority stakes in public companies and those companies ended up being put into play. It generated external high return... but the average tenure of our investments were very short. And nearly always 90% of the time got outbid by a third party when the businesses were sold... That short-term activism was profitable, but it was a poor strategic fit with our objective of being good permanent holders of vertical market software businesses. So we stopped doing it.

Buy and hold forever, we’re in it for the long run, and [PEMS] is another tool. The other part of the [PEMS] thesis is that the companies we want to invest in have the potential to benefit from an engaged minority shareholder. We want our [PEMS] or public portfolio companies to be run by people we respect — we want their incentives aligned with those of long-term shareholders. We like the businesses to generate high returns on incremental invested capital, and to return any excess capital to their shareholders.

PEMS is not the old short-term activism playbook, even though that worked out financially, and it’s possible that investees will get acquired and the “permanent” part of PEMS will turn out to be short.

The biggest open question is: Can they successfully influence companies they don’t control enough to improve them and unlock value?

And is 'permanent' really the right target? Or is it aspirational, like Buffett's 'ideal holding period of forever'? Will they really hold even if a company takes a wrong turn or gets wildly overvalued? 🤔

Bernie seems to confirm it really is permanent:

Bernie Anzarouth (CIO): I mean selling the businesses, if the price runs away with us, that just doesn't make sense tax-wise. It just would be tax inefficient. And I think what we would do is have or just see like-minded investors piling to the business that we're in. and just keep holding on to it for the long haul. We're not in the business of selling high-priced shares to people that are unaware of what's going on within the business. We're literally in there permanently.

But we’ll see how that turns out in practice, or if they change their minds over time.

On Buybacks 💵 ↩️

John Billowits: The way we think about it is we're using the same hurdle rates for making both decisions. We're buying businesses at a value that is far beneath what we're trading at and what other companies are trading at even after we fix them. So we still believe we can generate much higher returns by buying companies than we can by buying our own shares at these prices.

Mark Miller: Yes, I don't want to buy back shares. Definitely.

Customers as M&A Radar 📡

This one is from Lumine’s CEO:

David Nyland: So we’ve got some big customers worldwide, big brand names and -- they have a lot of intelligence. And so we learn a lot by speaking to them by finding out what the problems are, and obviously now supporting a portfolio of companies that sell into those customers. But also as they navigate their assets, they’re important assets, they start to share with us ideas about what else we could acquire to help them provide security with some of those assets that are in transient ownership at this point. So you have to kind of earn the position to have that conversation.

It takes some time, but the power of that relationship is unbelievable.

In fact, customers may want them to consolidate a space because it makes things easier and more predictable for them:

David Nyland: We mainly get new logos through acquisitions right? It’s very hard to go into a large media or telco business and become a new vendor. They want less hurdle. They want consolidation.

And if there’s something risky in the environment that they’re going to want us to do it. They’re not going to want some new name company that they don’t know. So they will always give us the first chance, so we can move quick, we should be able to capture that business.

Not a bad position to be in.

It’s kind of software as distilled customer trust, to riff on a metaphor used by Mark Leonard. The code matters, but the customer intimacy may matter more.

If you’re newer to Constellation and want a primer on the company, check out the podcast I did with my friend MBI (🇧🇩🇺🇸). It’s a few years old now, so it doesn’t include the latest developments, but I think it gives a lot of context on the business:

Andrej Karpathy Joins Anthropic Pre-Training Team 😮

Anthropic’s winning streak continues. One of the essential minds in AI wrote:

Karpathy has moved around a lot over the years, but clearly not randomly. He has been:

• Internships during his PhD:

  • Google Brain (summer 2011)

  • Google Research (summer 2013)

  • DeepMind (summer 2015)

• Then one of the founders of OpenAI

• Then at Tesla to lead Autopilot and be the director of AI

• Then at OpenAI again (mid-training and synthetic data work)

• Founded Eureka Labs to focus on AI education (2024–2026), where his videos have taught AI fundamentals to more people than probably anyone.

Now he’s joining Anthropic’s pre-training team.

Nicholas Joseph, the head of pre-training at Anthropic, wrote: “He'll be building a team focused on using Claude to accelerate pretraining research itself.”

Claude training Claude. The recursive loop 🔁. Andrej has been working on Autoresearch lately (82k GitHub ⭐s!), a project that uses agentic loops to optimize the performance of models automatically. Will he work on a scaled-up version of that?

Demis Hassabis is an Angel Investor in Anthropic 🏆🫡

This reminds me of how Jeff Bezos is an early investor in Google (he invested $250k in 1998) and, if he kept it, would be a billionaire even without Amazon.

The FT writes:

Sir Demis Hassabis, the founder of Google DeepMind, was an early investor in Anthropic, a previously undisclosed stake [...]

People familiar with the matter said Hassabis was an angel investor in Anthropic

And that’s probably not his only valuable personal angel investment:

Hassabis, who sold his London-based AI lab to Google for £400mn in 2014, is also an angel investor in businesses founded by former colleagues.

This includes Inflection AI, launched by DeepMind co-founder Mustafa Suleyman before he joined Microsoft in 2024, and Ineffable Intelligence, founded by longtime collaborator David Silver. [...]

Start-ups founded by former DeepMind employees include well-funded companies such as Mistral, Harvey, AMI Labs, Recursive Superintelligence, Latent Apps, Reflection AI, Cursive AI and Orbital Materials, among others.

Well, good for him. It does create an interesting conflict, as Anthropic is both a competitor and a big customer of Google, though. Not that he doesn’t have a much bigger stake in Google’s success, but it’s still a piece on the board. ♟️

I wonder if Demis was involved in the decisions at GCP to sell a boatload of TPU capacity to Anthropic a little while ago. 🤔

🤰📲 Is Fertility Dropping Because of Smartphones? 📉

I’ve long covered the fertility beat. It’s a big problem for humanity to be below the replacement rate in most places and still dropping. We could mitigate the problem by curing some of the diseases of aging and extending lifespans (and most importantly, healthspans), but that won’t replace creating new people.

There’s a very popular narrative right now that cellphones are to blame, and it makes a lot of intuitive sense. In fact, I'd be shocked if smartphones didn't have some impact. They reshaped dating, free-time use, and the nature of social gatherings. The carefree partying of the pre-pocket-camera age is gone. 📸

BUT

If we zoom out, we can also see that whatever impact came from Steve Jobs going on stage in 2007 is part of a larger process. 

The fertility decline has been running for over 150 years in some places, and was already rapid by 1970. And if we didn’t have Africa, the planet's average would look a lot worse:

The harder question is 'what would actually reverse the trend?' And I don't think anyone has a convincing answer yet.

🧠 Creative Practices Keep Your Brain Younger (Including StarCraft II) 🎮

This study asks: Do creative skills give you a younger-looking brain?

Researchers trained a brain-age model on EEG data from 1,240 people, then turned it loose on 232 with different flavors of creative expertise: tango dancers, musicians, visual artists, and StarCraft II players (Oh yeah!).

The metric they were looking for was "brain age gap." Does your brain activity look older or younger than your actual age?

Across all four creative domains, experts came out with negative gaps. Their brains "looked" 4–7 years younger than their chronological age, with an overall expertise effect of ~5.5 years.

There was also a small training arm: non-experts who trained on StarCraft II for 30 hours showed a ~3-year reduction in brain age gap, while an active control group showed nothing.

As an aside, the control group was trained on Hearthstone: “The Hearthstone game was selected due to its more rule-based and turn-based mechanics, with limited improvisation and creative play compared to StarCraft II’s real-time decision-making”.

There was a dose-response curve, so the more your game improved, the more your brain age gap did too.

The study’s proposed mechanism: creative practice strengthens or preserves connectivity in the brain networks most vulnerable to aging. Especially frontoparietal hubs (attention, motor control, coordination, visual processing). They also found higher local and global network efficiency, plus stronger biophysical coupling. The effects were bigger in long-term experts than in short-term learners.

Now let me throw a bit of cold water on this before you download Starcraft (well, you should anyway, or at least an instrument 🎸🎹).

Most of the expertise study is observational, so selection effects are still possible (maybe the kind of people who stick with tango for a while had different brains to begin with 💃). But however noisy the study is, it’s a pretty common-sense idea that creativity and learning difficult skills are good for you. It’s just nice to have one more reason to motivate us!

🚂 🎩 This LLM Only Knows the World Before 1931 📰 🕰️

This is a clever way to talk with the past:

we introduce talkie-1930-13b-base, a 13B language model trained on 260B tokens of historical pre-1931 English text. Additionally, we present a post-trained checkpoint turning our base model into a conversation partner without relying on modern chat transcripts or instruction-tuning data.

Very clever.

You might think pre-1931 wouldn’t give you much training data. We keep hearing that most text ever written by humanity was created in the past few years. But the talkie team is finding ways to scale it up significantly:

talkie is the largest vintage language model we are aware of, and we plan to continue scaling significantly. As a next step, we are training a GPT-3-level model, which we hope to release this summer. A preliminary estimate also suggests we can grow our corpus to well over a trillion tokens of historical text, which should be sufficient to create a GPT-3.5 level model—similar in capability to the original ChatGPT.

GPT-3.5 was the model used by the original ChatGPT, so while it won’t be anywhere near the frontier, it should be interesting to chat with (especially since modern algos and hardware should give it some advantages over the original GPT-3.5).

Why pre-1931?

Because, as of January 1, 2026, US works published through the end of 1930 are in the public domain.

One of the big challenges is to avoid ‘temporal leakage’.

That sounds pretty Doc Brown, but all it means is that in such a large pile of documents, some will have bad metadata, be mislabeled, mis-dated, of some old documents have modern footnotes. That kind of thing.

🎞️ Treasures of the Past: Why You Should Make Your Kids Watch Old Movies 🍿

Last weekend was a three-day weekend in Canada.

On Sunday night, we had a family movie night. We watched Groundhog Day (1993, Bill Murray), which was my kids’ first time seeing it. And, well, my wife and I have no idea how many times we’ve seen that film because it’s almost impossible to say. 😅

After you've seen it once, you feel like you've seen it multiple times. After a few times over decades, the only way to tell if a specific memory is real is by checking how unfamiliar the very beginning and very end feel (they're the only parts that play once).

In any case, my kids loved it. It was a nicely teachable moment. We had a good discussion about the difference between doing things because you think that’s what others want, and doing them just because they are the right thing to do, to grow and help others. It sounds a bit trivial when you write it out, but it’s profound, and a great thing to discuss at that age.

Then on Monday, my wife went out with the 8yo, so the 12yo and I stayed home and we watched…. Arrival (2016, by my boy Denis Villeneuve! 🫎).

I was really looking forward to it, and it didn’t disappoint. I hadn’t seen the film in a few years and really enjoyed it, but most importantly, my son LOVED it. He said something like: “When I have kids, I’ll be showing this to them when they’re old enough!”, which is a cool sentiment and nice endorsement of the film.

He also said he wanted to rewatch it so that he can now see things differently, now that he knows the ending, and that he wants to show it to his little brother when he’s old enough.

It also generated some great discussions about time and language. But also, about why it’s important to go back and watch older films, if only because there’s going to be a lot more good ones if you pick and choose from the past 60 years or whatever than if, like many people, you mostly just watch recent things from the past 2-3 years.

Same for music, same for books. 📚🎶

I’m glad to be sharing these moments with my kids, and helping open their minds to a wider horizon in my own little way.

I see my age in my children.

🛀💭🦷 Invisalign as a microplastic delivery system?

I wonder if plastic aligners have been tested for how much microplastics they release while they’re slowly rearranging your face-bones.

At least they’re not exposed to high heat or UV rays too much, which are generally factors that make plastics degrade faster. But having had these things in my mouth for a year, it’s hard not to wonder what happens when you add up plastic + saliva + mechanical friction + time 🤔

(not that I’m one of those people who believe that microplastics are the root of all evil, but I also doubt they’re good for ya)

So I looked it up, of course. 📄 🔍

Turns out several teams have actually run this experiment. The 2025 PLOS One study found that Invisalign aligners released the fewest microplastic particles among the brands tested, but the ones it did release were the smallest (12–23 μm long), which from a “could it cross a cell membrane” perspective is arguably the wrong direction to be best at (😅). The 2023 saliva-immersion study found all seven brands they tested released microplastics within a week.

So yes, plastic + saliva + friction + time does what you’d expect.

🕷️👦 We found a tick on my youngest son’s head.

He told my wife he felt like he got bitten on the back of the neck and there was a little bump. Thankfully, instead of just telling him “it happens, it’ll go away”, she had a look and saw the tiny little bloodsucker (I hate these just as much as I hate mosquitoes 🦟).

Luckily, it wasn’t engorged and probably hadn’t been there long, but we didn’t take any chances and checked with a pharmacist, got a 1-dose preventive antibiotic, and kept an eye out for any other symptoms in the following days.

This little adventure got me thinking about how much parasites and the diseases they carry must’ve sucked for humans in pre-modern times.

People got fevers, rashes, joint pain, facial palsy, neurological weirdness, chronic arthritis, and fatigue. But nobody could point to a clear cause, so it was all just folded into vague categories like rheumatism, palsy, summer fever, arthritis, wasting, “bad blood,” or hand-wavy stuff like “he was never quite right after that fever.”

(Honestly, 'pre-modern' is generous. Lyme disease wasn't recognized as a distinct syndrome until the mid-1970s, and its bacterial cause wasn't nailed until 1981–82 by William Burgdorfer at the NIH. The 1975 Connecticut cluster that finally cracked the case was initially mistaken for juvenile rheumatoid arthritis until two mothers, Polly Murray and Judith Mensch, kept calling the health department because too many kids in their town were sick. Borrelia burgdorferi has been in New England for ~60,000 years; we figured out what it does to us about 50 years ago. 🕵️‍♀️)

🤖🔐 AI Cyber Attack Capabilities: Doubling Every 4–5 Months (and Accelerating) 🔓🔑🏴‍☠️

It’s impossible to be precise about this, but it’s possible to get an idea of the rate of change, and this is what the AI Security Institute (AISI) has been trying to do:

In February 2026, we estimated that frontier models’ 80%-reliability cyber time horizon had doubled every 4.7 months since reasoning models emerged in late 2024, given a 2.5M token limit.

This was around half our November 2025 doubling time estimate, which was 8 months for both 50% and 80% reliability.

If a doubling every 4.7 months WASN’T fast enough for ya 😅

Claude Mythos Preview and GPT-5.5 have since significantly outperformed this trend. At the time of writing, it's unclear whether Mythos Preview and GPT-5.5 represent an isolated break from existing rates of progress or are part of a new, faster trend.

Mythos Preview and GPT-5.5 have large upper-bound error bars due to near-100% success rates on our narrow cyber suite’s longest tasks, even with the 2.5M token limit. Our tasks are also not long enough to determine how sharply the models’ reliability would deteriorate at higher task lengths. This places some of the latest models at the limit of what our narrow test suite can measure.

And the kicker: “Without the 2.5M token cap, success rates are so high that time horizons become impossible to calculate.”

😬

On April 7th, Anthropic wrote:

How long did it take us to get ready for Y2K? Patching all software is much more complex than fixing a single known bug.

Palo Alto Networks, one of the big security players, recently said:

For the last several months, we have had early, unbounded access to the latest frontier AI models. What we’ve seen from that vantage point has made it clear that the window for organizations to get ahead of what’s coming is shorter than most leaders realize.

We have moved past the era of incremental AI improvements into a threat landscape shift. Our testing has revealed a step-change in capability that demonstrates an intuitive understanding of software vulnerabilities. [...]

The latest frontier models, including OpenAI’s GPT-5.5-Cyber, Anthropic’s Mythos and Claude Opus 4.7, and the specialized variants emerging across major labs, represent roughly a 50% improvement in coding efficiency over their predecessors. That number sounds incremental, but in practice, it’s the threshold at which AI crosses from a helpful assistant into an autonomous operator.

They see four main categories that, when happening all at the same time, redefine the “modern threat landscape”:

• Vulnerability Discovery at Scale: Frontier AI is exceptionally effective at identifying vulnerabilities across massive, complex codebases. In [Palo Alto’s] testing, three weeks of model-assisted analysis matched a full year of manual penetration testing, with broader coverage.

• Exploit Chaining & Synthesis: What is more consequential than individual discovery is the models’ ability to think like an attacker. They link multiple lower-severity issues into single, critical exploit paths, seeing full-stack logic, including SaaS and public-facing surfaces, in ways traditional scanners cannot.

• Attack Cycle Compression: In AI-assisted scenarios, the time from initial access to exfiltration has collapsed to as little as 25 minutes. Detection and response measured in hours is no longer a viable standard; single-digit MTTR (Mean Time to Respond) is the new floor.

• The Unsupervised Attack Surface: Rapid AI development and decentralized innovation are creating a massive, unsupervised attack surface in real-time. As local AI agents become commonplace, every desktop is now effectively a server, yet most organizations lack visibility into the code their own employees are generating and deploying.

(Worth noting: Palo Alto sells security products, so they aren’t exactly a disinterested observer. But they also won’t do well if their customers get PWNED)

Even the NSA, an agency that surely has seen it all, is reportedly impressed:

Gold, silver, platinum, palladium, heck, throw in rhodium, ruthenium, and iridium too. Or how about diamonds, rubies, emeralds…

But zoom out a little.

Gold is star-stuff. Platinum is star-stuff. Diamonds? Carbon + pressure. On Neptune, it literally rains diamonds. ☔

These are all over the universe, forged by nucleosynthesis in supernovae and kilonovae, the universe's heavy-metal foundry. 💥

But wood? Wood requires life. A very specific kind.

It’s way cosmically muuuuuuuch rarer than gold, even if it’s locally plentiful enough to burn for heat. 🔥

I’m not sure where I first heard this idea. Maybe in The Expanse? They nail the implication:

In that world, asteroid mining has made metals abundant enough to build whole off-world economies, but real Earth wood becomes an absurd luxury. A real wooden desk on a space station is a flex: a fossil of sunlight, air*, rain, and biology, dragged up the gravity well and carried across the void. 🌳🚀

📊 Amazon's Goodhart Moment: How Employees Inflate Their Token Usage

I knew this was coming. I wrote about it in Edition #628.

Amazon employees are using an internal AI tool to automate non-essential tasks in a bid to show managers they are using the technology more frequently.

The Seattle-based group has started to widely deploy its in-house “MeshClaw” product in recent weeks, allowing employees to create AI agents that can connect to workplace software and carry out tasks on a user’s behalf, according to three people familiar with the matter.

Some employees said colleagues were using the software to automate additional, unnecessary AI activity to increase their consumption of tokens — units of data processed by models. (Source)

Similar to Meta, Amazon introduced targets for more than 80% of its developers and has been tracking AI token consumption on internal leaderboards.

Predictably:

Amazon told employees that these metrics won’t be used for performance evals, but employees don’t seem to believe it.

This has to be going on in so many companies right now.

The minute you put a number on a leaderboard and tell people their bosses are watching, you've turned the metric into a target. Goodhart's Law doesn't take weekends off.

🪑 The AI Pricing Shift: Seats → Seats + Metered Usage 📊📈💳

Another “hey, I wrote about this!” 😅

One way that AI's all-you-can-eat buffet era is slowly ending: the change from per-seat pricing to seats + consumption. Microsoft’s CFO Amy Hood said this on the last earnings call:

suddenly, if you think about getting work done and being more productive, it’s thinking about being a seat or a worker plus an agent. And when I think about that model, I start to think about it as a license business plus a consumption business and really applying far more broadly than I think people have thought about that.

And so it starts to mean that over time bookings will actually also look a little different. It will still have that per seat license logic, but it will also have a meter, just like you see in Azure.

And it may not all flow through bookings in the same way. You’ll just bill for usage. And if that usage has great value to customers […] then you’ll keep spinning and keep using those agents if they’re adding direct value or growth to your business.

We’ll see if the transition is as long and messy as the on-prem vs SaaS transition, or if this will be speedrun through at AI deployment speeds 🤔

🇺🇸 Elon Musk’s $119bn Terafab Plans 🏗️🏗️🏗️ 🐜

It’s still mostly just an idea, a plan, but the numbers are pretty mind-boggling: According to filings, the first phase will cost “at least $55 billion” and the full thing is planned for “up to $119 billion”.

I suppose there’s a certain benefit to having extremely high-multiple stocks at SpaceX and Tesla. I mean, as I just wrote about, SpaceX’s IPO looks like it could come out at 265x adjusted-EBITDA. And Tesla? Revenue has been pretty much flat since 2023, yet the stock trades at 125x EV/EBITDA and at a P/E of almost 400x.

If you can print that currency, swapping a bunch of it to invest in a megaproject is probably the thing to do. And there are few megaprojects America needs more than leading-edge fab capacity.

Right now, the chosen process technology is supposed to be Intel 14A, so at least he’s partnering with someone with a long history of chip manufacturing and not entirely reinventing the wheel. But it’s not exactly an easy industry to get into, even with the right partners. Musk would be Intel's first external 14A customer for a node that's still under development. There's high execution risk on both sides.

But hey, this kind of hardware moonshot is a better fit for Musk than AI software. If this has any chance of creating a ‘USSMC’, I wish him luck! I’ll believe it when I see it, though.

💰 OpenAI Has Already Sent Microsoft ~$31bn in Revenue (and counting…)

Let's set aside Microsoft's OpenAI equity stake for a moment (the 27% it got for its $13bn investment, currently worth about $228bn). Just the revenue generated by OpenAI between ‘23 and ‘25 adds up to an estimated $31.2bn:

The $30 billion revenue estimate suggests Microsoft’s revenue from OpenAI-tied products has accelerated over the past year. As of March 2025, Microsoft had generated only about a third of that total—$9.5 billion—from its OpenAI partnership, executive Michael Wetter testified in a deposition last year in Musk’s lawsuit.

Microsoft could generate many times the $30 billion figure in the coming years, based on spending commitments OpenAI has made to use Microsoft services. [...]

OpenAI paid Microsoft the vast majority of the roughly $23 billion it spent on renting AI servers between 2023 and 2025 [...] the bulk of the revenue Microsoft has gotten from OpenAI-tied business from 2023 to 2025 comes from that $23 billion the AI lab spent on server rentals. Additionally, about $2.5 billion has come from Microsoft’s sale of OpenAI models to its cloud customers, an API known as the Azure OpenAI Service (Source)

Going forward, the recently renegotiated agreement preserves Microsoft's 20% revenue-share rate but caps total payments at $38 billion through 2030. That’s down from the prior deal that could have produced as much as ~$135bn. Based on OpenAI's growth, the cap is expected to be hit around 2028. But OpenAI has also contracted to buy $250B in Azure services…

🍁⚛️ Ontario Begins Early Work to Add 4.8 Gigawatts to the World's Largest Nuclear Plant 🏗️ 📐

Ontario is writing a CAD$300M “let’s get serious” cheque to Bruce Power for Bruce C, a proposed new nuclear station next to the existing Bruce A and B reactors on Lake Huron.

To be clear: this is pre-development money, not construction money.

This funds the homework: technology selection (no reactor design picked yet but there are five candidates: the new MONARK CANDU, Westinghouse’s AP1000, EDF's EPR, Hitachi-GE’s ABWR and BWRX-300 SMR), workforce planning, site-prep design, cooling water strategy, the federal Impact Assessment, and engagement with the Saugeen Ojibway Nation.

That's a long homework assignment 😅

This is actually Bruce Power's second swing at this. They filed and withdrew a similar Bruce C application between 2006 and 2009, then focused on refurbishment instead. So the precedent says pre-development isn’t a guarantee.

Bruce Power's current refurbishment program is a success story worth highlighting. Two of six Major Component Replacements are done: Unit 6 in 2023 and Unit 3 construction phase completed in February 2026, with return-to-service expected later this year. Both on budget and ahead of schedule, including through COVID. That's wildly atypical for Western nuclear (eg. Vogtle, Hinkley Point, Flamanville-3).

Back to Bruce C: If it all works out, we’re talking about 4,800 MW of new dispatchable, clean baseload capacity. It would make the Bruce complex the largest nuclear generating site on Earth by a lot.

(Bruce already holds the “largest operating” title; Japan’s idled Kashiwazaki-Kariwa is bigger by rated capacity at 8,212 MW. Bruce + C would land around 11,200 MW.)

The Ontario Ministry of Energy is claiming $238B in GDP contribution and 18,900 construction jobs. I don’t know if it’s inflated, but I know that Canada is one of the rare tier 1 nuclear nations with a full supply chain in the country, so if they pick the CANDU, the economic benefits will be large.

Worth zooming out: Bruce C is just one piece. Ontario is also doing the $12.8B Darlington refurbishment (Unit 1 back 5 months ahead of schedule), Bruce Life-Extension (Units 3-8 through 2033), Pickering B refurbishment ($6.2B), four BWRX-300 SMRs at Darlington ($20.9B, first SMR in any G7 country), and early planning at Wesleyville (up to 10GW).

The province is quietly running the most ambitious civilian nuclear build-out in the Western world. 🇨🇦🫎

With electricity demand climbing, this kind of dispatchable clean capacity is what attracts hyperscaler data centers and reshored/friendshored manufacturing. 🏭⚡️👨‍🏭

Energy is Life™️. Ontario typically runs ~60% on nuclear. The provinces and states that lock in big chunks of dispatchable clean baseload now will look very smart in 10 years.

⏱️🏃‍♂️ Humanity’s Journey to the Sub-2-Hour Marathon

It took a while, but we did it!

(and by “we”, I mean not me… My wife is running a marathon in two weeks, but I’ll be cheering her on from the sidewalk)

At this year's London Marathon, two runners broke the 2-hour barrier:

• 🇰🇪 Sabastian Sawe: 1h59mins30secs

• 🇪🇹 Yomif Kejelcha: 1h59mins41secs

Incredible!

This detail: Sawe's first half was 60:29 and his second half 59:01. He ran the second half faster than the first 🤯

Watch at least the finish. It gives me chills!

Can you imagine the mixture of pride AND disappointment for Kejelcha?

You do something historic… but 11 seconds behind the person who will be in all the history books. Usually, I’d say that you should compare yourself to your own potential, but in this case, it’s literally a race against others 😅

Using Codex, I made the graph above to visualize what it took to break the 2h barrier (it took me a while to get the graph to generate cleanly and to fact-check all the data points… AI’s not yet one-shotting this).

If we go further back, the first sub-3h was Johnny Hayes (👆) in 1908 at the London Olympics. Spiridon Louis was the first man to run a “marathon” under 3 hours: 2:58:50 at the 1896 Athens Olympics, but that race was about 40 km, not the official 42.195 km distance.

It then took over a century to grind from 3h to 2h! I wonder how far humanity can push it going forward 🤔

It’ll be interesting to see how long it takes for the 2h record to fall on the women’s side (if it happens, I mean, some records endure for decades). Ruth Chepngetich holds the women's marathon world record at 2h09mins56secs (Chicago, October 13, 2024), though she's currently serving a 3-year doping ban that expires in April 2028. The record stands because the positive test came months after the race 😅 The fastest "clean" mark behind it is Tigst Assefa's 2h11mins53secs (Berlin 2023).

💾 Patch Your Stuff + Google Catches First Mass-Exploit Attempt with AI-Developed Zero-Day 🏴‍☠️

There have recently been updates to iOS and macOS 📲 💻

The changelog lists 50+ security fixes for iOS 26.5 and ~70 for macOS Tahoe.

If you’re on Apple’s platform, make sure to keep up to date and install patches, and the same applies if you’re on Windows or Linux.

Apple doesn’t say if these patches were the result of working with Mythos to find security holes (Apple's a Project Glasswing partner), but while security is never NOT important (sorry for the double negative, but it sounds punchier that way ¯\_(ツ)_/¯ ), now’s a particularly great time to start taking it more seriously.

Google’s Threat Intelligence Group (GTIG) just announced that they had identified for the first time “a threat actor using a zero-day exploit that we believe was developed with AI.”

Kinda ironic: GTIG identified the AI-generated exploit partly because the Python script contained a hallucinated CVSS score. For once, AI hallucination saved the day.

To be clear, catching someone doesn’t mean it was the only one. This is just the tip of the iceberg, and it’s likely to be a pretty big iceberg because there’s just so much surface area out there, and there’s an asymmetry between attackers and defenders (the former just have to be right once to get in, while the latter has to be right every time to keep the perimeter secure).

In the long run, AI is likely to make cyber security better by patching holes and augmenting human analysts. But the road is likely to be bumpy on the way there 😬

Another finding from GTIG:

Threat actors now pursue anonymized, premium tier access to models through professionalized middleware and automated registration pipelines to illicitly bypass usage limits. This infrastructure enables large scale misuse of services while subsidizing operations through trial abuse and programmatic account cycling. [...]

By leveraging anti-detect browsers and account-pooling services, actors are attempting to maintain high-volume, anonymized access to premium LLM tiers, effectively industrializing their adversarial workflows while subsidizing their operations through trial abuse and programmatic account cycling.

On the psyops front, a new tactic that GTIG identified is using real media clips but modifying them with AI:

GTIG uncovered activity linked to the pro-Russia IO campaign “Operation Overload,” involving video content that leveraged suspected AI voice cloning to impersonate real journalists.

In identified instances, the actors appear to have manipulated an authentic video to convey a false message. This content appears to splice original vertical videos with montages and fabricated audio to create false and misleading messaging. The close voice match to the original suggests the use of AI tools

🤠🤠💰🚂 Butch Cassidy and the Sundance Kid : The Buddy Movie’s Original Chemistry 🚲 🇺🇸🇧🇴

I watched Butch Cassidy and the Sundance Kid (1969) with my kids. It was their first time. It’s one of my favorite films, but I was a little worried how they would handle the 1969 pacing. The full credits roll before a single scene, and there’s an extended travel montage that is just sepia photos.

But they LOVED it!

My oldest and I have been quoting lines back and forth all week. William Goldman, who famously said ‘Nobody knows anything’ about Hollywood, sure knew how to write memorable dialogue (see also: The Princess Bride, All the President’s Men).

What stuck with me on this rewatch: the bad guys are barely characters. The famous “Who are those guys?” posse is shot as a distant, mythic thing. Director George Roy Hill deliberately refused to give them faces. The real antagonist of the film isn’t a sheriff or a gunslinger. It’s the 20th century: railroads, payroll systems, Pinkertons with telegraph lines, institutions that never get tired and can keep coming after you. Charm doesn’t scale against institutions.

There’s a true story about the real Butch that Goldman loved. He called it “the best character introduction I ever came across,” but didn’t end up using it. Butch was offered parole by the governor of Wyoming on the condition he go straight. Butch basically told him: “I don’t want to lie to you, I can’t promise that. But I promise I won’t rob banks in Wyoming.” He got a deal. I mean, how charming do you have to be to get that offer? That episode is the whole story in miniature.

That film runs on Newman and Redford’s chemistry. It set the modern buddy movie template. Buddy duos existed before (Hope and Crosby, Abbott and Costello), but those were mostly vaudeville routines. Butch Cassidy established the version that endures: two leads whose rapport is the engine, the plot exists to give them things to do. 2+2=5. Countless others have copied the structure. Almost none have matched the chemistry.

Redford himself liked the role enough that he named his Utah land after the character. That land became the Sundance Institute, which became the Sundance Film Festival (you may have heard of it).

The freeze-frame ending perfects the trick. The film doesn’t deny their deaths. It freezes them as legend at the exact moment history was about to make them corpses.
