In an hour-long discussion on Twitter Spaces on Wednesday night, Twitter owner and Tesla and SpaceX CEO Elon Musk reflected on the motivation behind his newest artificial intelligence venture, China’s relationship with the U.S. and the likelihood of AI creating a dismal future for humanity.

Musk participated in the discussion with two key members of Congress who sit on the House Armed Services Committee and the Select Committee on the Chinese Communist Party: Reps. Ro Khanna, D-Calif., and Mike Gallagher, R-Wisc. The event was billed as a conversation about the future of AI and came on a day that Musk launched his own new AI company, xAI.
