There really is a meme here I think, and it relates to ego. Having said that, I definitely do think there is truth in massive variations between programmers, though I personally think that is a combination of a small pre-requisite talent (the ability to code at all, which I think a surprisingly small amount of people have - simply a genetically determine brain configuration), and mostly attitude + hard work. For exam…
Ego is what bring us down from the top of cockyness mountain as well. The fall would make us humble (and hopefully learn something from it).
At the end of the day, I believe human should learn to live with each other than to shove one another.
