Feb 11 : Elon Musk overhauled the management of his artificial intelligence startup xAI ahead of a planned initial public offering that could rank among the largest ever, a week after merging the company with his rocket firm SpaceX. The reorganization follows the recent departures of several co-founders at the three-year-old AI company, leaving only half of the startup’s original 12 co-founders and raising questions about stability as Musk pushes to compete with OpenAI and Google on all fronts.
