genius and madness, it's nothing new.

almost all great artists and scientists were somewhat bi-polar.

i believe it's an evolutionary thing. Not everyone who is close to madness can manifest their genius. Only the "fittest" ideas (and implementations) survive.

also, people who are considered normal by social standards do not have the motivation or guts to foray into experimental territories such as this.
