So assuming that you made the decision after you know what you know currently, would you be content knowing you could no longer be apart of something great that would need genius. Basically being a Trump or a Kubrick.
Just because I have friends doesn't mean that I'm any more or less intelligent than if I had no friends. Isolating yourself does not make you more intelligent than being sociable, if anything it brews arrogance, and makes you you overestimate how smart you really are. So no, I wouldn't change a thing about myself.
