Your assumptions are wrong. Egotism makes a programmer weaker, not stronger. Those who consider themselves rockstars are, in my observation, never the best. And they're a pain to work with because they get defensive about ideas. The great programmers I've known have also been the most fun to work with. It's a team sport.
