I feel like one of the more important things to take away from this is the wildly different degrees to which various students use ai. Yes, 90% may use it, but there is a huge difference between "check following paper for grammar errors: ..." and "write me a paper on the ethics of generative AI," though an argument could be made that both are cheating. But there are things like "explain Taylor series to me in an intuitive way." Like someone else here pointed out, a 1-2 minute conversation would be a very easy way for professors to find people who cheated. There seems to be a more common view (I see it a LOT on Lemmy) that all AI is completely evil and anything with a neural network is made by Satan. Nuance exists.
