Cybertruck is incredible in-person 🤯 It feels like a glimpse into an awesome future.

Messi is going to the World Cup final!!!!! Great game, heartbreaking for England. Two legendary teams. What an amazing world cup🤯 LFG!

SpaceX will help expand humanity out to the stars. It makes me excited for the future! Huge congrats to Elon and the SpaceX team 👊

Here's my conversation with Anthony Kaldellis about the deep history of the Roman Empire in the west and the east (the Byzantine Empire). This was a truly fascinating conversation with a lot of wisdom for the modern world and for the future of human civilization. The Roman state lasted over 2,200 years. If we want to understand human nature, the modern world, and how humanity can flourish, it is valuable to study history, especially the history of why societies survive and why they collapse.

Happy Birthday America! To me, the greatest nation on Earth. 250 years of loudly arguing our way toward a more perfect union 😂 We're in this together, I love you all! ❤️ PS: World Cup has been amazing. US in the round of 16, LFG! Also, I'm a long-time huge fan of Argentina and Messi, but Cape Verde vs Argentina was one of the greatest games I've ever seen. That is what the World Cup is all about!

Long hike in LA hills with @hubermanlab, one of my favorite humans (& best friends) on Earth. I enjoy hikes where you can be in nature and still, at some high-elevation points, see the city in the distance below. In those moments, it all seems so surreal. How did we clever humans build all of that? We went from hunter-gatherers to a civilization that can space travel and has a chance to colonize other planets and reach out toward the stars 🤯

I spent last week at Neurips (the big ML/AI conference) and had hundreds of amazing technical conversations with old friends and new. Beyond the technical, I'm deeply grateful for the love from all the folks who stopped me in the hallways and in the street to say kind words and share their research & life stories with me. Once again, I felt like the luckiest kid in the world. I took a lot of notes at the conference, and will try to write up my takeaways, here on X and on a new Substack (see links below). Additionally, I will likely do lecture(s) on the state-of-the-art in AI as I've done in the past. If this is interesting, please indicate your interest in the "topics & suggestions" form below (see links in reply). I'm trying to get back to occasionally publishing in conferences & journals (because it's fun & makes me happy). As I said previously, grounding myself in engineering tasks many hours a day, humbles me to the reality of the world. For me, this is important to do regularly. I'm collaborating with a few incredible people at MIT and Caltech on human-robot interaction research, with humanoid and quadruped robots. It's a bit of an experiment to see if I can find the time to both do deep prep for each podcast episode (sometimes 100+ hours) and also do the serious research grind required to publish interesting papers. Like everything in life, when max effort is applied, even short-term "failure" leads to growth & lessons-learned, which is a win. So really, the only way to fail is to not try with max effort. What a crazy life this is… Truly, I'm a lucky dude. I love you all ❤️

I got to train with Khabib Nurmagomedov (@TeamKhabib) yesterday. This was an honor of a lifetime for me. He's a great fighter & leader and a great human being. From a grappling perspective, I don't think I've ever experienced this much top pressure in my life. I'll post the footage of the training in a few days. And also we'll do a long podcast (and dub it in multiple languages). In general, it was an incredible experience to train with the team and get to know many of the fighters from Dagestan. All are great people.

Here's my conversation with Jeff Kaplan, a legendary Blizzard game designer of World of Warcraft and Overwatch, which are two of the biggest, most influential games ever made. Jeff is one of the most genuine & awesome human beings I've ever met: kind, thoughtful, hilarious, and still & forever a gamer through and through. This was a truly fun & inspiring conversation. We talk about it all: the lows, the highs, the memes, the details of the game design process, and the new game he's been secretely working on: The Legend of California. I got a chance to play the game with Jeff, and it's incredibly beautiful (and fun). You can wishlist it on Steam now. I can't wait to play it with all of you!

It was an honor to hang out with Jensen Huang, CEO of @nvidia, and do a long-form podcast with him. Really fun & fascinating technical deep-dive conversation on & off the mic. One of the most brilliant & thoughtful human beings I've ever met. NVIDIA is the most valuable company in the world by market cap and is the engine powering the AI revolution. Podcast probably out tomorrow (Monday) unless I get stuck in too many interesting conversations while running around in SF ;-) PS: I haven't checked my messages in days. Sorry for slow replies 🙏 Trying to stay deeply focused at in overwhelmingly intense time & barely hanging on. Love you all ❤️

Humans just launched into space, on their way to the moon (flyby around it). It'll be farthest humans have ever traveled into deep space 🤯 Congrats to all the incredible engineers & teams involved! LFG!!!!!!!

This life is fucking amazing. I'm so grateful to be alive, with all of you on this miracle of a planet. Oh and I'm sorry if I fuck things up sometimes. I'm a flawed human. But I promise to do whatever I can to try to add some more understanding and love to this world. After the world leader convos I get attacked intensely by all sides, and many disparate online communities. It has led to some really low points for me mentally. But I don't matter. I'm listening. I'll do better. And I'll try to find the strength to do more of them, always with rigor and backbone, seeking to truly understand. And despite accusations, I do extremely high amounts of research, sometimes 100+ hours for a conversation. Ask many of my previous guests. But when I come to the table, I put all that aside, and make it all about the other person. I don't ever try to sound smart. I know the vastness of my ignorance. But I'm trying. Sometimes I do fuck up and sound like a douche, or do something incredibly cringe. And I hate myself right after. But I'd rather fail and embarrass myself a million times, than not do what my heart says is right. And besides world leaders, historians, CEOs, engineers, etc, this year I want to travel the world and talk to a lot more everyday people on and off the mic. This is something I've wanted to do for a long time. Anyway this is written while on I'm on a 10 mile run, probably procrastinating, since to type I have to walk and not run 🤣 But I did just get stopped by a super smart and kind girl who works at a humanoid robotics company here. And she asked if she can give me a hug to thank me for being me. Sometimes the universe sends you a message that even a dumb dude like me can almost hear. I really needed that today. Thank you for the hug and the kindness 🙏 I'm just hoping she was real and I didn't just imagine that 🤣 Then again if I went full crazy might as well enjoy it! Back to the run. I love you all! ❤️

I'm traveling the world for a bit, starting with China but then hopping around the globe, anywhere. Open to any adventure. No plans, only a backpack. Hoping to meet & get to know humans from all walks of life. The pic is from a long hike on the Great Wall. For me, as a fan of history, this was an epic experience. In China, first I'm visiting a few big cities & talking to engineers at the heart of China's AI revolution. After that, if feeling crazy enough, I'm hitchhiking (first time) across rural China for a few weeks. Hitchhiking because I think it's the best way to meet rural folks who I would otherwise never get the chance to meet. I hope to do the same in US and other places. I have a request, if you have a travel recommendation, fill out the form(s) below if you feel like it. Or share with folks who might have advice about such travel. Form 1 - travel recommendation: If you can, recommend to me an interesting place I should visit anywhere in the world. For this, fill out form 1. Not touristy stuff, but something off the beaten path, that tourists may not know about, but is legendary. It could be as remote as meeting a herder in the mountains who is a local legend. Asia, Middle East, Europe, India, South/North America, Africa, Australia, anywhere. In China, I'm hoping to visit maybe Heibei, Shanxi, Shaanxi, Gansu, Sichuan, Yunnan, etc, so recommendations for spots to visit are helpful. Form 2 - coffee: If you want to grab a coffee with me anywhere in the world, fill out form 2 (please don't use form 1 for that). Anyway, I hectically tossed stuff in backpack. Realizing I don't have a clear plan of any kind, which is probably the only way to do it. LFG. Love you all ❤️

I got to spend all day today with Jensen in Taiwan: talking with thousands of engineers and eating street food at a night market. Jensen is received as a rockstar in Taiwan, like it's Beatles in the 60's. It's mind-blowing and fun to watch. But most importantly, through all the interactions and all my conversations with him, he remained the same humble, kind, thoughtful, funny guy he always was, even as a kid who went to these same night markets many years ago. Btw, we tried a crazy amount of different street food. It's legit some of the most delicious food I've ever had. I can't wait to share video of it, including a ton of our conversations and hangout. When I can pause for a moment from all the travel to edit the video, I'll post it. Can't wait to continue talking to Jensen and engineers at Computex this week, and exploring more of Taiwan, and of course roaming the night markets for some more delicious street food. Days like these, even more than usual, I feel like the luckiest kid in the world. Love you all! ❤️
