Seriously, Musk looks like an almost fatty 50yo. Zuck is 39yo and in great shape, so it should be easy for Zuck to win. But I don't care and will not watch it or follow it or whatever :)
Zuckerberg is a surprisingly decent jiu jitsu practitioner as well as being younger and in better shape, so I’m reasonably certain he’d mop the floor with Musk.
The audience who get to watch to to rich morons mash each other's faces in? Realistically though Musk is taller so he would probably have an advantage. But also who cares, this is just a stupid publicity stunt – a pathetic attempt to claw back some popularity after they've both recently fucked up so badly and publicly lost huge amounts of money.
