The wealthy have a huge incentive to want unskilled teachers. They’d probably rather go back to the days when only the wealthy were educated at all, but creating a bigger gap between the quality of education of the rich and the poor is a passable short term goal for now.

Remember, the point of a company isn’t to make a product, it’s to make a profit. It’s more profitable to have a dumb population that unquestioningly buys whatever you advertise to them, and if you sell a few crappy AI teaching robots along the way, that’s just a cherry on top.
