I mean, watch it yourself and decide. I’d find it difficult to see how anyone could come away with anything other than the more-or-less self-evident notion that Ma is a moron, Musk is extremely intelligent, and they’re both egomaniacal, albeit expressed pretty differently.
I don’t see a reason to compare Ma’s complete lack of reasoning skills to Musk’s absurd tweets. That’s whataboutism. Sure, Musk is all sorts of fucked up in his own way, but he’s no idiot; besides, that isn’t what we’re talking about here — unless for whatever reason you’re trying to defend Ma (which, again, seems like a pretty pointless exercise if you watch even a few minutes of that video), Musk’s weird ass behavior (which wasn’t exhibited in the video in question) has no bearing on this discussion.
I don’t have a dog in this race and would really prefer to never meet either of them, as they both seem pretty insufferable. My point is simply that Ma is damn near indefensibly stupid and (unfortunately, a trait that seems on the rise amongst prominent people in the world today) a poster child of the Dunning-Kruger effect.
