In a move that’s sure to shake up both the tech and  sports worlds, Elon Musk, the self-proclaimed master of all things bold and boundary-pushing, is now setting his sights on the world of competitive sports. According to the latest rumors, Musk is planning to propose a new rule that would ban biological men from competing in women’s sports. Yes, you read that right. Apparently, after revolutionizing space travel, electric cars, and social media, Musk has decided that gender equality in sports is his next frontier.

Sustainable transportation options

This bombshell proposal comes just after Musk’s recent Twitter rants (because, of course, he’s on Twitter) about the fairness of allowing men to compete in women’s categories. Forget about electric cars saving the planet or the potential for colonizing Mars—this is the issue that has apparently captured his attention. Perhaps it’s because, between building rockets and running companies, Musk simply has too much time on his hands.

So, what’s next? Are we going to see Tesla-sponsored sports leagues that only allow men with electric cars to compete, or will SpaceX finally put its resources to good use and create an intergalactic, gender-neutral Olympics on Mars? The possibilities are endless—though, based on Musk’s track record, it’s probably best not to rule anything out.

At this rate, Musk might just end up as the world’s first tech mogul to make both space travel and sports controversies his side hustle.
