When the only strategy to understand the universe is truth-seeking, you build a truth-seeking machine

@tszzl one of the poasters of all time

300k … wauw 😳

@tszzl @Liv_Boeree it’s not intuitive that GDP and human wellbeing would become less correlated over time as humans are playing a lesser role in the economy?

@Liv_Boeree nick land is wrong, technocapital serves man

Spitballing here but I suspect the economy is already a form of alien intelligence that serves itself as a primary goal & survival of humans is secondary at best. And as it becomes more and more digitised it will be entirely taken over by agentic AIs who are better than any human at maximising their own capital (& thus power) in that environment, and humans will become diminishingly able to influence or extract value from that economy. So to survive in any meaningful way, we need to reinvent a more human-centric economy that capital maximising digital agents cannot speed-run & overtake.

@woj_zaremba congratulations!

Life update — I’m moving to the OpenAI Foundation to lead AI resilience. AGI will bring tremendous benefits and potential disruptions, such as impacts on children and youth, model malfunctions, emergent bio-risks, and more. AI resilience is about minimizing these disruptions so society can fully realize the benefits. openaifoundation.org/news/update-on…

@JaimeAlns @xai 🐐

It’s one of those: today was my last day at @xAI. xAI has been a tremendous formative experience for me, building the API, Grok.com, and everything in between, it’s been crazy and hectic, but overall amazing. I’m especially grateful to everyone I’ve worked with, @TobyPhln and the team in London, you’re the most talented team I’ve ever worked with. I’ll be cheering from the sidelines, really excited to see what the xAI team is going to come up with next!

@tbpn @travisk the rise of mario

.@travisk says AI will make human labor even more valuable and in-demand than ever before: "Let's say the entire world - everything in our world - was automated, except for plumbers. You had machines making buildings - you would basically have like a thousand buildings a day." "How valuable would those plumbers be?" "Each and every plumber would be like LeBron. Why? Because plumbing would be the long pole in the tent to progress. You can't get those thousand buildings unless you have a plumber." "And by the way, you'd get so much efficiency everywhere else that you'd need millions of plumbers." "Humans [are going to] become more and more valuable because they will be the long pole in the tent to progress - and that progress is going to accelerate and get faster and more robust."

@imhaotian @elonmusk my multimodal goat.. get some rest

I left xAI earlier this week. It was a difficult decision. The past two years have been an intense, fun, and deeply rewarding journey, and I accomplished things I could not have imagined two years ago. Thank you @elonmusk for the opportunity and for everything I learned at xAI. Thank you @Guodzh for the trust you placed in me and for all the days and late nights we worked through together. And thank you to the entire Omni / Imagine team: thank you for your trust, and for growing together with me. It has been an honor, and I am incredibly proud of what we achieved together. I feel fortunate to have had the chance to work with all of you. At xAI, everything feels possible. I had the chance to work with and learn from some of the most exceptional people I have ever met. I was able to explore across domains: from pretraining to post-training, from language models to multimodal, from perception to generation. Joining xAI was one of the best decisions I have ever made. @grok imagine is special to me. Building video generation models, where I started with almost zero prior knowledge, from 0 to No.1, as an IC and as a lead, alongside an extraordinary team, and shipping it as a great product used by millions, all within 6 months, at age 28: I feel proud. But now it’s time for me to move on. I’m burnt out, and I know my happiness is no longer maximized in my current state. It is sad to say goodbye, but it is just the right time for a change. Best wishes to the Imagine team, you are absolutely the best, and you deserve the best. I will cherish all our memories for the rest of my life. For now, I’m taking a break and giving myself time to figure out what comes next. Posted from Hawaii.

@Guodzh thanks for everything, legendary carry

Last day at xAI. Wild journey past three years but excited about next chapter. Thanks all for the love and support yesterday. So many friends made along the way and I will miss you all!

@TobyPhln @xai @elonmusk incredibly grateful for your leadership, thank you toby

Three years, thousands of PRs, and a million jokes. Today was my last day @xai. To the team: you rock, no one burns the midnight oil better. To @elonmusk, thanks for taking me on board. I've learnt more about execution, speed, and product perfectionism than I could ever have imagined. Thanks for everything. My next priorities: sleep for more than 8h, write down all the things I've learnt (I have a list), and then think about what I want to do next. @gork wdyt?

@Yuhu_ai_ Thank you for inspiring us

I resigned from xAI today. This company - and the family we became - will stay with me forever. I will deeply miss the people, the warrooms, and all those battles we have fought together. It's time for my next chapter. It is an era with full possibilities: a small team armed with AIs can move mountains and redefine what's possible. Thank you to the entire xAI family. Onward. 🚀 And to Elon @elonmusk - thank you for believing in the mission and for the ride of a lifetime.

Took a break from Claude coding to write a little story babuschk.in/posts/2026-01-…

@allgarbled it's quite bad at solving unfamiliar problems

Trying to 100% claude code my side projects without reading the code has moderated my LLM psychosis slightly tbh. But only slightly.

@andrewqu @shuding nice, looking forward to trying this out tn

Excited I was able to play a small part in helping @shuding ship this! While helping him compile React best practices into an Agent Skill, I realized I was copy pasting skill setup instructions from all the major coding agents To save all of you time, I built `npx add-skill`

@reecebrah @chongz taking notes

“Buddy” is an interesting term because there’s a generational gap If anybody over 50 calls you buddy He’s just being nice If anybody under 50 calls you buddy He’s being max level condescending And borderline inviting a physical altercation

@chongz chongz with the public dd

This is a 9 month old company, even the founders haven't vested 💀

@cHHillee @dylan522p @tszzl @iScienceLuvr @BjarturTomas 😂

@dylan522p @tszzl @iScienceLuvr @BjarturTomas If you didn't ask why is there a button titled "reply" under your post??

Nolan is just not a good screenwriter. Amazing director. Bad writer. Oppenheimer was not good, exhibiting every vice of a biopic with some novel ones thrown in. The absolutely phenomenal soundtrack and Cillian Murphy redeem it. Robert Downey Jr.’s performance was cartoonish.

@cvegavaladez @ibab Loved working with you Cristian, thanks for being an amazing recruiter

@devindkim @ibab It was great partnering with you Devin! Thank you for all your contributions, excited to see what’s next! 🚀

September was my last month at xAI! I joined as one of the first members of the post-training team in 2024 and eventually led research tooling, where we built some of the world’s best systems to accelerate Grok’s development. On my first day, I was at the whiteboard with @ibab and @TheGregYang mapping out the data collection infra for Grok-1.5 and beyond. After sketching it out, I said, “It would be great to have two other engineers. We could grind this out in a few months." This felt ambitious, since competitors had already spent years investing in similar infrastructure. They looked at each other and then replied, “But we hired you to do this!” I quickly realized this culture was the driving force behind xAI’s success. Back then, it felt more like a side project than a company - just a handful of us huddled into a conference room we called the “bunker.” Around me, hardcore engineers like @makro_ai, @TobyPhln, or @Guodzh were routinely pulling off feats that would require entire teams elsewhere. Their example inspired me, and I somehow ended up delivering the initial architecture in under a month. Towards the end of my time at xAI, I spent more of my focus on RL and model training. There are too many people to thank, but I owe a special thanks to @ZihangDai, @ericzelikman, and @hendrycks, the ones who made that work possible through their collaboration over the past year. The most talented people I've met are also the ones who work the hardest. I’ll always be grateful to @elonmusk for the opportunity. Looking forward to what’s next!

@CPU_FANS_MAX @ibab Thanks Seth, life is not the same post-technobabble era

@hendrycks @ibab Looking back, the past 1.5y would not have been possible without you. Thank you for your continuous support and tireless work in advancing AI safety at xAI

@devindkim @ibab Thank you so much for all your hard work and help. You are tactically gifted, are very sociable, and are so driven that you worked nonstop.

@KatiaEarth @ibab Thanks Katia! I will miss all the incredible things we accomplished together

@devindkim @ibab It was wonderful working with you, Devin! Thanks for everything, you were always very supportive.
