Elon Musk testified on Tuesday in an Oakland federal court that he can be trusted on AI safety because he warned former President Barack Obama about its dangers during a one-on-one meeting in 2015, where he "spent an hour" warning Obama about AI, which "no one was really using" at the time. Musk also testified that Larry Page, then Google's CEO, called him a "speciest" for being "pro-humanity" over AI in 2015, and that "Larry Page refused to speak to me ever again." Musk said he cofounded OpenAI to create "a counterbalance to Google," which "did not seem to care about AI safety at that time." Musk was the first witness in his civil trial against OpenAI and Sam Altman, seeking more than $100 billion in damages and a request to unwind the for-profit structure of the $850 billion company behind ChatGPT. The lawsuit, filed in 2024, accuses Altman and Greg Brockman of deceiving him into donating $38 million toward a nonprofit mission that was abandoned for private gain. Musk testified that a court loss "will give license to looting every charity in America."
