OAKLAND, Calif.—Tesla CEO Elon Musk took the stand on April 28 as the first witness in a federal civil jury trial in Oakland, California, accusing OpenAI CEO Sam Altman of defrauding him and betraying the company’s founding mission: to operate as an open-source nonprofit dedicated to advancing artificial intelligence for the benefit of humanity.
The lawsuit stems from a bitter feud between the two tech titans over the organization that they co-founded in 2015, which has since become one of the world’s most valuable and powerful players in the global artificial intelligence (AI) race.
