I wonder where do you take your experience from. I do pretty much all of what you described and while yes, there are definitely jerks around, there is no correlation between the level and jerkness. Maybe it's just hard to become "the best" while being a jerk, although I know quite a few world class climbers who are jerks and the best and who are humble dudes and the best. In fact, we use IRC a lot for PyPy development and I think we're trying to be welcoming to other people, especially the newcomers, but then again, it's a self-judgement. What I've seen correlation is the age (although there is definitely no rule here either). Typically, while you're being 16 and you climb say 7B, you think you're the best and you look from above towards people who climb 7As. And there are some people climbing 8Bs I know who are as bad as when they were 16.
