My post was a bit tongue in check. I don't want to minimize the fact that Feynman was sophisticated. The main issue is that he didn't compete were other competed.

In an intellectual field where everybody tries roughly to do the same thing IQ picks winners. Again I simplify. Feymann had a quality of approaching problems differently then the rest. Feymann had a way to motivate himself to engage deeply in a playful way with physics at a level where there no obvious use in going down a certain path of thoughts beyond having fun.
