But to make it a meaningful experience (and get out of it with a PhD) you need a wholly different skillset. It's clear that you have never seen a kid who destroyed the productivity of a whole office because he treated his colleagues Just Wrong, and that you have never seen a fellow who just couldn't transfer what he learned in class to real-life application.
That's harmless. But if you have someone who continuously messes up shared equipment, leaving it for the next person to fix, and who won't improve their attitude, no matter how often you tell them, that's deadly for morale.
