Elon Musk's lawsuit against OpenAI and Sam Altman begins in federal court in California this week, with a nine-person jury set to hear claims that Altman swindled Musk out of millions and betrayed the company's original non-profit mission. Musk, who co-founded OpenAI in 2015 but left in 2018 after a power struggle, is seeking billions in damages and wants Altman ousted. OpenAI denies the claims, saying Musk is motivated by jealousy and regret for walking away from the company. The trial will feature testimony from Musk, Altman, Microsoft CEO Satya Nadella, and others, including Shivon Zilis, mother of four of Musk's children.
