I think the real divide we're seeing is between people who saw software as something that is, fundamentally, improvable and understandable; and people who saw it as a mysterious roadblock foisted upon them by others, that cannot really be reasoned about or changed. And oddly, many of the people in the second category use terminology from the first, but fundamentally do not believe that the first category really exists. (Fair enough; I was surprised at the second category.) It's not about intelligence or whatever, it's a mindset or perspective thing.
