I share some of your sentiment, yet...not. I was one of the top three students of my graduating high school class. I turned down a National Merit Scholarship, in part to go be "normal" and walk away from the sick inculcation with being an obnoxious brainiac and social outcast, hiding my insecurity and emotional pain over the social end of things behind a wall of contempt and superiority. I have managed to wash off a lot of that shit, but being a nobody for years and becoming quite poor -- even homeless -- has failed to make me normal by any stretch of the imagination. I have given up on being normal.

I still hope to find ways to put out useful information that will benefit people who are more "normal" than I am and I do have my concerns about the world being designed and run by so many people who absolutely cannot relate to the day-to-day experiences of most of their target audience/customers. But I don't know that hoping for "normal" people to do the design work is in any way useful.

I don't know what the answer is, but it seems like a lost cause to want people to do brilliant design work and also be normal. If you are that brilliant, you simply are not normal. Period.
