I've switched over to Rex as my primary terminal and AI system.

So no more Kitty, Ghostty, Herdr, or any of that.

But I was having trouble getting an invite to the iOS app (email delivery issue).

So I just made my own client.

I just make my own software now.

I have a new concept I call The Bitter Wall.

- The Bitter Lesson tells us to stop micromanaging AI
- Basically: let smarter AI figure out the steps
- But there's a limit to this
- The output can only be as good as our articulation of what we want

Thanks for telling me the part most people skip.

But the part that I skip when I see that sentence is the rest of whatever you were going to say.

It’s the number one AI tell right now.

@sortofadev I started messing with agents in 2023. and was already doing some pretty functional stuff in 2024. By last year, I already had my harness and was doing many employees worth of work.

Just a reminder for people who are freaking out about the AI takeover stuff in 2027...

Whenever we get RSI or ASI or whatever milestone you care about, that's one date...but it's not the only date that matters.

It doesn't say anything about the integration time for getting that tech into the actual world.

My friends and I have been doing AGI-adjacent stuff for years already, and yet there are companies still refusing to use AI, or only using it as a chatbot.

No matter how big of a jump we see in 2027, dispersion will still take time.

@ShaneBOly That's fully autonomous; the assisted number is much closer to all.

This post by Anthropic is massively overlooked, and these are my biggest takeaways:

- Claude now leads 26% of Anthropic's AI R&D work. In February it was under 1%

- AI collaborates on or leads over 90% of that R&D work. In August 2025, going by the chart, it was about 4%

- About 30,000 AI agents do research and engineering at Anthropic at any one time (on one platform)

- Those agents made over a billion decisions in one month. 1 in 47,000 got blocked

- Monitors flag ~100,000 agent transcripts a week, and only ~50 reach a human

- To build the index, Claude agents read staff Slack and docs and mapped 15,000 R&D tasks

- Claude agreed with humans more often than humans agreed with each other (59% vs 35%)

- Agents get their own identities that survive model upgrades. They coordinate on an open message board, so they can check each other's work

It really does look like 2027 is the takeoff year, as so many have been saying.

I'm overjoyed to announce that I'll be joining @Netflix as a Senior Security Engineer (L5), focusing on detection engineering and platform security! 📺

It has been a dream of mine to work for Netflix since college. Netflix's open support of FOSS and security research has always stood out to me, and I've admired the security org's work for years.

I'm excited for what's ahead.

@theo Opus as main and Fable for smart stuff is the only way to do this without reintroducing limit stress.

One way to tell if you have a really good harness / system is if it takes longer for you to see the improvements from new models.

If you already have high standards that are represented and enforced in your evals, model improvements are more subtle. @poteto @mattpocockuk
