>Now, everyone basically has a personal TA, ready to go at all hours of the day.

And that's a bad thing. Nothing can replace the work in learning, the moments where you don't understand it and have to think until it hurts and until you understand. Anything that bypasses this (including, for uni students, leaning too heavily on generous TAs) results in a kind of learning theatre, where the student thinks they've developed an understanding, but hasn't.

Experienced learners already have the discipline to use LLMs without asking too much of them, the same way they learned not to look up the answer in the back of the textbook until arriving at their own solution.
