The problem is that AI will not provide 1:1 tutoring; mentoring will be a luxury limited to the elite classes. The large majority will get the education equivalent of personalized ads.
The true insight and guidance that a good mentor can provide, based on the specific needs of the student, is already rare in academia but still possible - everyone remembers that brilliant teacher that made you love a subject, by explaining it with insights you could never have imagined. This will be missing in AI teachers (though it opens a career for online mentors who monitor students' learning and supplement it in areas where it's lacking).
