I don't think I was arguing for LLMs. I wish nobody used them. But the argument against a student using it for assignments is significantly different than that against people in general using them. It's similar to using a calculator or asking someone else for the answer: fine normally but not if the goal is to demonstrate that you learned/know something.

I admit I missed the joke. I read it as the usual "you hypocrite teacher, you don't want us using tools but you use them" argument I see. There's no need to be condescending towards me for that. I see now that the "joke" was about the unreliability of AI checkers and making the teacher really angry by suggesting that their impassioned email wasn't even their writing, bolstered by their insistence that checkers are reliable.
