God we live in such a fucking absurd timeline, and we know it’s only going to get less sensible
My money's on Zuck, he clearly works out whereas Musk is a gamer loser that very clearly does not.
There's also the fact Zuck has been doing MMA for over a year too.
I honestly really hope this happens because I would like to see Zuck actually kick the shit out of him but I think Musk will realise he's gonna get his ass kicked and back out. Watching Zuck choke him out into unconsciousness would be gold.
