Elon Musk on Space GPUs, AI, Optimus, and his manufacturing method

John Collison and Dwarkesh Patel sit down with Elon Musk to discuss why the future of AI isn’t on Earth, but in the "always sunny" vacuum of space. Between pints, they discuss the brutal physics of scaling—from the "farcically cheap" solar cells coming out of China to switching Starship from carbon fiber to stainless steel—as well as the “infinite money glitch” of humanoid robots, China, and DOGE.
