I only heard about high temperature superconductor theory through one seminar + lab, and I too got the impression that nobody really understood this stuff -- at least not good enough to make solid predictions, and to explain it to a physics undergrad. I'm glad somebody else shares this sentiment, and it wasn't just me being dense.
