I have found this with my kids as well. I have an AI writing tutor that they use but only one of the two actually likes engaging with it. The other gets easily disengaged.
Some kids will be able to learn at a record pace with AI, others will need to be brought along in the usual ways via good teaching that fosters engagement.
My son does not have a great opinion of any edtech -- AI or not. I would wager that if you asked any kid his age they'd rather have better air conditioning than another expensive bit of software they hate using.
