Relentless pursuit of building the Best possible thing irregardless of silly things like profits, market share and time to market sounds very much like engineers I've run into. As does eschewing standard or off the shelf solutions in favour of something you made yourself since you're obviously much smarter and anything you build yourself will be much better since it will be designed around solving your problem. Not to mention that many engineers I know love building and designing from scratch rather than using something already available, simply because that's much more fun.
So it's a double-whammy of Cult Personalities who are all afflicted with Not Invented Here syndrome. I can see how that would lead to some massive problems.
