Elon Musk is back in the news again. (Really, does he ever leave the news?) Last week, Musk announced a new artificial intelligence venture called xAI. The timing of the launch is odd considering Musk still runs Tesla, SpaceX, Neuralink, Boring Company, and Twitter. Twitter in particular is causing him headaches, with both its sagging business and increased competition from rivals like Meta’s Threads. All of these developments are happening in the shadow of what feels like a lazy subplot on a bad sitcom—a proposed mixed martial arts cage match between Musk and his rival, Meta CEO Mark Zuckerberg.
