No that's not exactly what I meant. It's not that "If AI can do X then X is worthless", but rather in _this_ case it's inappropriate.

Homework should be a part of the collaborative process of learning (as others above have already elaborated on). If teachers are having a problem with AI generated homework being submitted, it shows that the system is broken because they couldn't have been collaborating with students on their learning then.
