I'd change that to "the future will be wonderful for whoever is able to afford this technology." AI has the power to give some people a massive competitive advantage over others, and some people will be willing to spend a lot to keep that to themselves. It'll be democratized to an extent but you can be absolutely certain "AI tutors" will be a market, and people at lower incomes won't be able to afford the best ones (which is fine, it's just like human tutors. That's capitalism.).
