I'm joining SpaceX and xAI, working closely with Elon and team to build superintelligence. Together SpaceX and xAI combine physical and digital intelligence under a leader who understands hardware at the deepest level. Add a high-agency culture with frontier-scale resources, and you get the possibility to achieve something truly unique. I’m excited to advance the fields I’ve obsessed over for years, from robotics research to building AI models on the founding teams of Mistral and TML. Both were extraordinary journeys with extraordinary people that shaped how I think about building intelligence from the ground up. Grateful for everything that brought me here and can’t wait to get started.

The good news? We’re winning universal childcare faster than anyone expected. The bad news? Ms. Rachel and I have to find some new song inspiration…

This ESPN+ broadcast has been terribly bad. Being played at Climate Pledge Arena, you would expect better.

If Trump seizes Greenland from Denmark, does that mean that all Americans will be entitled to: Free healthcare with no deductibles? A free college education? 52 weeks of paid parental leave? 5 weeks of paid vacation? Because that’s what everyone in Denmark and Greenland has.

Yeah
