I think this sort of in-group superiority effect is likely to occur for pretty much any male-dominated obsession with a large body of associated arcane knowledge. For example, gamers have in-jokes like "the cake is a lie".

At the same time, I have worked as a programming tutor and there are some people who suck really hard at programming. They're probably just stupid though. For example, I tutored a kid who absolutely couldn't program for beans but did well in a physics class we took together. But I think it's likely that he did well through pattern recognition, aping example problems and so on. In programming, you really have to understand what's going on.
