Elon Musk, the owner of Twitter, challenged Mark Zuckerberg, the CEO of Meta, for a cage match, which started with Musk's reply to a tweet, saying that it seems like Earth will be exclusively under Zuckerberg's thumb. In response, Zuckerberg posted a screenshot of Musk's tweet on his Instagram with the caption "send me location." A tweet screenshot later appeared on Twitter. Musk replied to it, saying that he would do it if it was for real. In 2017, he had a similar spat with Zuckerberg, criticizing his understanding of AI.
