Your post seems to suggest that we shouldn't use Docker and instead we should hire... smart people? Those are two entirely separate things.

Docker goes a long way to solving exactly that problem, though. It allows you cover any variety of peculiarities and history by tailoring each and every app's environment appropriately. You seem to dislike Docker because it is buzz-worthy. Sometimes the buzz is onto something.
