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 as Musk seeks to halt the ChatGPT maker’s ongoing conversion into a for-profit company. Musk, an early OpenAI investor and board member, sued the artificial intelligence company earlier this year. Musk 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 is filing its response Friday.
