To add: Genius isn't even a predictor of success. Granted, intelligence is a useful tool, its only one of many things that govern success. Sometimes "genius" can be in impediment to success.

Humans are hive minded despite our best attempts to assert otherwise. A modern computer or a modern bridge can't be built from scratch by one person. A genius can certainly help raise the bar, but a cohesive unit capable of achieving the end result is going to be a better optimization strategy.
