Otherwise it's been with in-person conversations and I didn't record them, there's a spectrum to how completely they suggest I allow AI.
Everything else you said I more or less agree with. Obviously if someone wants to cheat they're going to do it, but I feel that until we restructure the job market to not take GPAs as seriously (which I think I'd probably be onboard with), we should at least have cursory efforts to try and minimize cheating. I'm not saying we have to have Fort Knox, just basic deterrence.
I'm not an adjunct anymore, partly because I took stuff way too personally and it was kind of depressing me, partly because it was time consuming without much pay, but largely because I realized that most universities are kind of a racket (particularly the textbook corporations are a special kind of evil).
