This is why I have a bit of an aneurysm whenever all of these wildly disparate things are lumped together under the umbrella of "STEM". Notably, we keep medicine in the acronym, but in almost all discussions, doctors and nurses and everything else that would fit under that heading are forked out already. - Edit: derp, it's Math, not medicine, but there's an indication of how brain-rotted I've gotten trying to follow this subject.

Each of them is it's own world with it's own context and it's own problems.
