Teaching should turn into conveyance of taste. The teacher should help figure out what needs to be examined and how to examine; help figure out ways to close the gap between the textbook and reality. AI can't do those things well yet, and perhaps it never will be able to.
Maybe all education will get more and more similar to e.g. learning an instrument.
You can get everything from YouTube videos, sure. But a good teacher will help with things like knowing how to get a good repertoire for your skill set, what bad habits not to develop that will cripple your ability to learn more complex pieces over time, etc.
I think expertise in hard subjects will only become more and more valuable (as always), and thus harder and harder (and more expensive) to achieve.
Sucks, but its true. In my case, if there was a test that required me to disassemble an engine top to bottom, claude would be mostly useless.
