A 7-year-old rivalry between tech leaders Elon Musk and Sam Altman over who should run OpenAI and best avoid an artificial intelligence ‘dictatorship’ is now heading to a federal judge. The development comes as Musk seeks to halt the ChatGPT maker’s ongoing conversion into a for-profit company. Musk was an early OpenAI investor and board member. But he sued the artificial intelligence company earlier this year. He has since escalated the dispute, adding new claims and asking for a court order that would stop OpenAI’s plans to convert itself into a for-profit business more fully. OpenAI filed its response in court Friday.
