Students/people who are interested in learning a particular subject are doing just fine learning it from already available material, be it books, videos, MOOCs, etc. They may or may not use AI, but AI won't make a huge difference for these type of people.
For people who are not interested in learning, AI won't do sh*t. Because the problem is not that they don't have a tutor available to them; the problem is that they don't have motivation to learn. I am not being judgemental here: it is perfectly understandable, for example, why a poor kid may not have motivation to learn.
A few years ago, MOOCs were touted as the next best thing to democratize education and make it available to underserved populations around the world. This did not happen. Some research shows that MOOCs are mostly used by an already-educated group of people who are interested in further learning. I think learning with the help of an AI tutor would be no different: its users will not be the intended ones.
