I'd add another factor: neurology. Our brain don't like to break accumulated "knowledge" to replace it. Especially if it's just to recreate a different mess without a global improvement in insight. And if this occurs too often.. it feels as breaking your leg every time your bones heals.. I don't get angry when I read a new topic, even if complicated, it's a motivating pleasure even.. but trying to reverse yet another vaguely specified build system .. not so much.
