A war of words between tech billionaires Elon Musk and Mark Zuckerberg has led to the two men challenging each other to a cage fight. The dispute has broken out after Facebook parent Meta Platforms Inc. META hinted it was planning to launch a social media platform that would be a direct rival to Twitter, which Tesla Inc.TSLA CEO Musk acquired last October for $44 billion. Musk has been trolling Zuckerberg on Twitter — where else — and said on Wednesday, “I’m up for a cage match if he is lol.” Zuckerberg responded on his Instagram with a screenshot of the Musk message and the response: “Send me location,” AFP reported. Meta confirmed to AFP that the message was from Zuckerberg. Zuckerberg has recently been posting videos of his training sessions in the martial art jiu jitsu. Musk and Zuckerberg have long been rivals, who have publicly clashed over their views on a range of issues, including AI.
