What's on Elon Musk's mind? In this exclusive conversation with head of TED Chris Anderson, Musk details how the radical new innovations he's working on -- Tesla's intelligent humanoid robot Optimus, SpaceX's otherworldly Starship and Neuralink's brain-machine interfaces, among others -- could help maximize the lifespan of humanity and create a world where goods and services are abundant and accessible for all. It's a compelling vision of a future worth getting excited about. (Recorded at the Tesla Texas Gigafactory on April 6, 2022) Just over a week after this interview was filmed, Elon Musk joined TED2022 for another (live) conversation, where he discussed his bid to purchase Twitter, the biggest regret of his career, how his brain works and more.
