The lawsuit between Elon Musk and OpenAI has entered the cross-examination phase, with OpenAI's lawyer, Savitt, scrutinizing Musk's past communications. Key evidence includes Musk's decision to halt his $5 million quarterly payments to OpenAI in 2017 and his subsequent attempts to gain control by demanding additional board seats. Despite remaining on OpenAI's board, Musk allegedly began recruiting OpenAI staff for Tesla and Neuralink, as revealed through emails and text messages. During the cross-examination, Musk expressed frustration, accusing Savitt of asking misleading questions. The court session also highlighted discrepancies between Musk's testimony and his public statements, particularly regarding Tesla's involvement in artificial general intelligence (AGI). The trial is set to continue with further testimonies from Birchall and OpenAI president Brockman.
