The first week of the high-profile legal battle between Elon Musk and OpenAI saw Musk taking the witness stand, dressed sharply in a black suit and tie. He accused OpenAI CEO Sam Altman and President Greg Brockman of misleading him into investing in the company. During his testimony, Musk expressed grave concerns about the potential threats posed by artificial intelligence, suggesting it could lead to catastrophic consequences for humanity. He also acknowledged that his own venture, xAI, is essentially a refinement of OpenAI's models, raising questions about the future of AI development and safety.
