But the instructor is not applying their understanding in any way. By delegating the evaluation to AI, there is zero value add vs just asking ChatGPT to evaluate your knowledge and not paying $1000s or $10000s in tuition.

I'm not intending to say it's acceptable for professors to use AI entirely in their grading. They obviously ought to contribute. I realize I actually misread your original comment, thinking of "instructor can have AI do his job" as "instructor can have AI to help do his job." Sorry about that. Point being, I think the expectation for real human thought ought to hold for both teacher and student.
