Elon Musk mocked Mark Zuckerberg for his July 4 video after overtaking him on the billionaires list, stating he prefers working over having fun. This feud between the two escalated as Musk challenged Zuckerberg to a cage match last year, canceled due to lack of confirmation from Musk, and rekindled by Musk on Zuckerberg's 40th birthday. Despite briefly surpassing Zuckerberg in wealth, Musk's Tesla stock surge has now made him the world's richest again, with a net worth of $252 billion, leaving Zuckerberg behind at $181 billion.
