This has been an insane few days for AI: - GPT-5 & gpt-oss - Grok Imagine - Claude Opus 4.1 - Genie 3 - ElevenLabs Music The future is going to be wild 🤯

Huge thanks to all the open source projects that've made a lot of the tech we rely on in the world possible: Linux Git FFmpeg PyTorch & TensorFlow Apache & Nginx MySQL, PostgreSQL, SQLite Chromium & Firefox GCC & LLVM Docker & Kubernetes Also, all the open-weight LLMs... and all the programming language interpreters, compilers, and frameworks. I can list 100+ more "niche" open source projects I've used & loved (e.g., OpenCV ❤️). But I just wanted to give a continued big thank you to the open source community for everything you do for humanity 🙏

Here's my conversation with Jack Weatherford all about Genghis Khan and the Mongol Empire. He is the author of Genghis Khan and the Making of the Modern World and many other books on the Mongol Empire. This was a truly fascinating conversation!

Thanks @lexfridman for another super fun & wide-ranging conversation. We talked about the future of video games, the nature of reality, advancing science with AI, the path to AGI… and quite a bit more as usual! Always a blast, already looking forward to next time! 😀

Imagine if every pattern shaped by nature – like a protein’s fold or cosmic phenomena – is inherently learnable by AI. @DemisHassabis shares with @lexfridman that if AI can learn these natural patterns, we could open doors to new eras of scientific discovery. Listen now. ↓

Here's my conversation with @demishassabis, CEO of Google DeepMind, all about the future of AI & AGI, simulating biology & physics, video games, programming, video generation, world models, Gemini 3, scaling laws, compute, P vs NP, complexity, energy (solar & fusion), and much more. This was a fun & fascinating super-technical conversation. It's here on X in full and is up everywhere else (see comment).

I've spent this week in Dubai (first time) and made a lot of new friends, including this goat. Dubai is a beautiful place, unlike any I've ever been to, with super interesting people from all walks of life. What a wild ride this life is. I grateful for all of it ❤️

This was one of the longest, most interesting conversations I've ever had with another human in my life. Lots of great podcasts go deep, but @lexfridman takes you to the bottom of the Mariana trench!

Here's my 6 hour conversation with @dhh, a legendary programmer, creator of Ruby on Rails, author, and race car driver. This was a fun and inspiring conversation on everything from the future of programming & AI to the nature of happiness & productivity to the value of family, getting married and having kids. X limits video length to 6 hours. So this full convo doesn't fit (by a few minutes). So, the first 6 hours are here on X. The full version is up everywhere else (see comment).
