All 11 co-founders of Elon Musk's artificial intelligence company, xAI, have resigned, with the last departure being Ross Nordeen last Friday. Nordeen, who was closely working with Musk, played a key role in coordinating company initiatives. The exodus follows xAI's merger with SpaceX in February, prompting significant leadership changes. Musk acknowledged earlier this month that xAI is undergoing a complete restructuring due to foundational issues.
