The Globe and Mail reports in its Friday, May 15, edition that lawyers for Elon Musk and Microsoft-backed OpenAI presented their closing arguments Thursday in a landmark trial that could influence the future of artificial intelligence. An Associated Press dispatch to The Globe reports that Mr. Musk was a co-founder of OpenAI, which started in 2015 and went on to create ChatGPT. His lawsuit filed in 2024 accuses OpenAI chief executive officer Sam Altman and his top deputy of betraying a plan to keep it as a non-profit and shifting into a money-making mode behind his back. The trial's outcome could sway the balance of power in AI -- breakthrough technology that increasingly has raised fears about its potential effects on the economy, society and even humanity's survival. Mr. Musk is seeking damages and changes to OpenAI's business structure, as well as Mr. Altman's ouster from company leadership. If Mr. Musk wins, it could derail OpenAI's initial public offering plans.
