I don't think Buffet is just an outstanding stock picker. Stock picking is all chance.
Buffet is a great manager and he has the ear of the companies he invests in. That's where his talent really is.
Taleb is really enjoying the spotlight, though. He comes up with a dumbass strategy of buying teeny options and then waiting for catastrophes. He bled at least one fund dry that way, had one okay year (Universa or whatever it's called was up 38% - not much compared to what most trading companies were up in 2008), and he's been riding that "achievement" ever since.
His black swan thing is correct, but translated into a strategy, it's like a stopped clock.
