He's been pretty tame. But look at who we got to compare him too. People at that wealth are just insane. Zuckerberg could take a shit on his lawn in broad daylight and that wouldn't be too crazy for his class of people.
I'm also ignoring the whole turning the entire internet into his personal spy application that tracks every human and creates profiles of them without their consent. And lots of other messed up impacts his company has created. But as a person the guy comes across as next door neighbour vibes.
It looks like they got him on testosterone now though. That seems to mess with a lot of guys as they get older mentally. Maybe we're at the beginning of another melt down.
