Uh, gotta say I disagree there...
Art is, well, an art!! You can't teach art. And yes, although many things in this world IS linked to art, STEM is a teaching program that, uh, teaches. It's about sciences- things that can stay consistent (yes, math is a science) and can be taught to people, and the rules (although there have been many changes made in these studies over the past couple centuries!!) tend to stay the same as time will continue to move forward.
Anyways, just my two cents
