I believe that's what Isaacson tries to write about in the Jobs and Musk biographies, indirectly. He seems to think that being an asshole has nothing to do with being brilliant.

Personally, I think it has more to do with having an emotional hole. Creators who do so primarily for its own sake, be they musicians, visual artists, or coders, are different from those who want to rule the world. The latter may genuinely enjoy the craft, but it's often subordinate to the deeper need for validation (see: emotional hole). It's this need that makes people assholes, imo.
