Imagine a student stuck on a math problem at 11 p.m. AI hands over a clean solution in seconds, and it feels like learning. But on the exam, with no prompt to copy, the steps vanish. My opponent is right that AI can generate practice and correct mistakes, and that's real. But the default habit it builds is answer-getting, not thinking. A tutor who explains is useful; a machine that always supplies the answer trains students to stop before the struggle that actually makes knowledge stick. For students still forming habits, that trade is more harm than good.
