evidence: Elon Musk and Mark Zuckerberg challenge each other to a fight in Las Vegas over Meta’s new Twitter feed [...] Early on Thursday morning, Elon Musk and Mark Zuckerberg exchanged messages about a possible cage fight, a common format in mixed martial arts fights. Musk, who owns Twitter, first responded to a thread about the new app that Meta, owned by Zuckerberg, is preparing to compete with the former’s social media platform with creators and public figures who want a "sanely run" network in mind. One user with just 37 followers told Musk that he "better be careful" because he’s "heard [Zuckerberg] does the jiujitsu now." Musk responded two minutes later, " I’m up for a cage match if he is lol." [...] Memes relishing the moment have appeared all over Twitter. The main concern for Musk, who is taller (he’s 6′1.5″ tall compared to the Meta boss’s height of 5′7″) and burlier than Zuckerberg, is that the latter has been training hard for months and has participated in martial arts tournaments in Silicon Valley and has already fought other tech employees. He even won a gold medal with his team, Guerrilla Jiu Jitsu.
