I disagree. If, after you have been tutored, you perform well, but still need tutoring for the next year's exam in that subject, then you haven't been "tutored", you've been given a similar enough copy of the exam questions to train on.
As I keep telling my kids, good results is a side-effect of good habits. If you're half-assing things, it shows up in your results. If you studious and methodical, it also shows up in your results, just in a different direction.
AI is used primarily to half-ass things, do things without checking, getting good vibes by that sycophantic tone.
Get your kids into a rut of good habits, and they'll run in that groove forever, regardless of tutors or AI. Half-ass your way through life, then sure, they'll get fucked over by AI tutors too.
One huge issue IMO is that right now, around the world, most people are not taught at all how to learn for themselves nor how to critically think on their own. And that will indeed result in using it as a crutch and not a good tutoring tool.
