San Francisco/New York, April 28 -- The bitter legal fight between Elon Musk and the leading artificial intelligence firm, OpenAI, led by Sam Altman, may come down to a few pages in one executive's personal diary. "This is the only chance we have to get out from Elon," wrote Greg Brockman, OpenAI's president and a co-founder, in the fall of 2017. "Is he the 'glorious leader' that I would pick?" Brockman's diary entry is part of the thousands of pages of internal documents revealed in court since Musk, one of the original co-founders of OpenAI, sued the company, its chief executive Altman and Brockman in 2024. Musk is seeking $150 billion in damages from OpenAI and Microsoft, one of its largest investors, according to a person involved in the case, with proceeds going to OpenAI's charitable arm. Jury selection for the trial is planned for Monday in the Oakland, California, federal court, with opening arguments expected on Tuesday. The documents offer a rare window into egos and personalities that have shaped OpenAI as it evolved from a nonprofit research lab in Brockman's apartment to a tech giant worth more than $850 billion. They also shed light on how the CEOs with the most power to shape generative AI think about the technology. The trial risks complicating OpenAI's plans for a potential initial public offering by casting doubt on its leadership. A drumbeat of unflattering disclosures could also intensify Americans' growing pessimism about AI technology more broadly. The case centres on Musk's claim that OpenAI, Altman and Microsoft betrayed OpenAI's original mission as a nonprofit to benefit humanity by forming a for-profit entity in March 2019, 13 months after Musk left the OpenAI board. Musk said the defendants kept him in the dark about their plans, exploited his name and financial support to create a "wealth machine" for themselves, and owe damages for having conned him and the public....
