What kind of fresh hell does the sentence "undercut the professor" come from?

Teaching isn't a race to the bottom. You don't undercut teaching by giving more lessons, just like you don't slight the hospital by performing CPR.

We are not really talking about teaching here.

		No, we’re talking about an intimate set of tensors, not a human being. A tree falling and killing someone isn’t tried for manslaughter. So I don’t care about a hypothetical teacher.
