Not the only one. I think most of his books are actually prolonged intentionally arrogant blog posts sprinkled with pseudo-science and weightlifting metaphors with the recurrent 'fuck you money' motif.

Black swan, the concept which brought him in the spotlight is somewhat valid but it's worth at most a chapter in a risk management book. But he milks the black swan cow to biblical proportions.

Antifragile is so longwinded it's an exercise in attention and patience. I think it's remarkable how he managed to fill so many pages.

In my view, Taleb resides close to Malcolm Gladwell and Seth Godin, the 'thought leaders' experts at rebranding/refactoring common concepts and milking the proverbial cow in publishing, speaking events, etc..
