I wonder if the problem is twofold: 1) a lack of education compounded by 2) the rapid evolution of computer systems.
Unix is a rare beast in that not just its philosophy but even its components survive to this day and remain relevant[1]. People in unrelated fields rebuild tools that could just as well be assembled using Unix's basic components, but they're just not aware of them. And why would they look for these antiquated tools? They've been trained to reasonably expect old tools to have been replaced by newer, better, more featureful ones.
