Five years at the spaceship. Wins, losses—growth. The greatest professional privilege of my career. Grateful for the people, the lessons…the mission.
Just getting started.

Hi, I'm Felix. I'm an eng lead working on Claude. I love watching people take flight and do things they never thought possible.
We often describe that as "being more ambitious" when using AI, which is tricky advice to follow. I wrote a tutorial:

say it with me now. experts are fake, smart generalists rule the world, everything is designed by people no smarter than you, and courage is in shorter supply than genius

We're hiring exceptional engineers to join the team.
No degree required. All we care about is you being smart and able to solve hard problems.
Total comp is $550k-$1.1M (job ad says something else, but ignore that).
Join Polaris, a new @GoogleDeepMind team designing the complex evaluation frameworks that will define the future of AI coding agents, and give you the autonomy to prototype architectures and publish research.
Experience? We care about how you think and build, not your “level.”

I’ve had 100s of engineers and new college grads ask me how to get a job at Apple. I tell them to go ship an app in the App Store and then I’d promise to at least hop on a call with them. Only 2 ever got back to me with a shipped app.
Most people won’t put in the work. Go put in the work.

And I’d like to personally invite you to come walk that mile with us, since the UI frameworks team is hiring! You can even bring your own shoes! 👟 jobs.apple.com/en-us/details…
Until you've walked a mile in their shoes, it can be hard to appreciate why the teams at Apple are so conservative with the API surface they expose.
But look at the navigation bar in iOS 17. Now look at it on iPhone Duo on iOS 27. It was a massive multi-year effort that required rewriting nearly all of UINavigationBar and UINavigationController.
Do I wish SwiftUI was open source? Yes. But the folks on the UI framework team have good reason for operating the way they do.
😂😂😂😂 I can’t believe they wanted me to delete Twitter. “The child George Bush personally left behind” is diabolical lmaoo

So proud to be part of the team that helped bring lab ordering to the redesigned Health app! 🎊 #AppleEvent
Sending lots of love to the Apple community on my last day as CEO. My title changes tomorrow, but the love I have for the Apple community never will. Thank you for being a constant source of inspiration. My gratitude is endless, and I’m excited for the next chapter!

Dentist did a 3D X-ray of my jaw before a root canal and said I wouldn't be able to open the raw data, it needs specialized software. It's 800 DICOM files. Asked Claude Code to make me a viewer. Two prompts later... this is nicer than what he showed me on his screen.
Wild take. So, distributing capabilities through abstraction users already understand means they aren’t using those capabilities?
Students don’t use TCP/IP, they use the Internet. They use Google Docs, not distributed cloud infrastructure.
TikTok? IG?
Hot take… isn’t it kinda crazy that nobody is really using AI Agents? I don’t mean software engineers or AI early adopters. I mean “college friends talking about it in group chat,” the feeling you got when everyone started using Instagram or TikTok.
These frontier AI models are *insane* (as are the harnesses & tool calls & the like). And every large tech co has an AI agents platform, not to mention all the YC startups doing vertical agents. Yet all of your friends and family outside of tech — who spend all day staring at their iPhones and get paid to work in browser tabs — don’t really care or find themselves using any AI agents yet.
Yes ChatGPT, Claude, etc. are extremely popular… but if you look at the engagement data the vast majority of people are still using these aI chat tools like a glorified Google + Grammarly. That’s why the AGI labs are all pushing desktop apps for Codex, Cowork, etc. so hard to non-technical ppl. And yes exceptions for lawyers and customer service but even those have some asterisks and exceptions to rule.
Look I’m not saying the ChatGPT moment for AI Agents is not coming… it most definitely is! Remember we pivoted from Arc to Dia precisely because we believe computing is going to be radically reimagined around these AI primitives. No doubt. But that’s my point: it’s just so surprising it hasn’t happened yet because all of the tech you’d need is there.
Again if you stop for a second and think about it… for all the press and money and hype and models and crazy ARR numbers… this “AI Agent” moment does not *feel* like the other breakthrough tech moments we’ve lived through (e.g. think the shift to Stories via Snapchat & Instagram, or shift to on-demand via Uber/Airbnb/Doordash).
Which is a long way of saying: if you can figure out the answer to “why” most people don’t care about AI agents yet (and have no enduring interest in using them) — especially since the models and harnesses are here and ready — the answer to that question will allow you to capture a lot of marketshare and make a lot of money in 2027.
Theoretically, the tech is ready for AI Agents to totally transform how we work and live our lives… but alas the general public dgaf… that’s the generational puzzle to solve for the next 12 months for anyone not working on the models themselves.
