SBF probably is a genius for some definition of genius. He was also eloquent and persuasive (imagine that, for a guy whose parents are both lawyers).

Doesn't mean he could/should run a business.

Many such cases of tech geniuses who have the mental capacity to deliver, and the verbal skills to advocate for their own power.. but not the mindset to actually deliver the things they've advocated for!

Pretty hard to screen for, and can do a lot of damage to an org as they siphon off resources from the teams of doers, squander them, and then take their ball & leave when it stops being fun.
