"The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore, all progress depends on the unreasonable man." -- George Bernard Shaw (1903)
Steve Jobs, patron saint of tech that he now is, was neither reasonable nor a pleasant person to work with or be around ($hole in today's parlance). (However, this changed considerably as he was nearing the end of his life.)
I strongly disagree with that take. Pushing the envelope does not require treating others like &hit. Also, there are degrees of "niceness", it's not a binary state.
