I don't really fully understand it either but Altman has been a questionable character for a long time.

I remember when he took over ycombinator, Paul Graham boasted "if Altman got dropped onto an island full of cannibals, within three months he'd be king of the cannibals." PG thought this was terrific but I thought "why the hell would you leave someone like that in charge of your VC fund?" Altman had gotten the spot running the firm after failing out of his startup. He failed out of ycombinator and then managed to do that thing where he inexplicably failed at bigger and bigger things raising more money somehow every time.

It sounds like that's what he's doing now quite honestly. Rumor is he's been beating around the middle east raising billions for a new AI chip startup. Honestly while Elon has normalized CEOs wandering off and doing other things, the fact is that for any normal employee that alone would be grounds for dismissal, especially if he was being evasive with the board about his plans.
