I’m from a US state with a 40% adult literacy rate (=above eighth grade reading level). At least there, none of those three things are even close to the root causes. The average school in the US outside of the big cities, especially the farther you get from the coasts, is just not fit for purpose — and funding only seems to ever go down (not that throwing money at the problem alone would solve it).

Honestly — and I’m not being at all utopian/overvaluing the present state of the technology — I think AI is one of the few prospects for even just marginal improvement, especially since it’s accessible by phone. Much as I wish it wasn’t the case, it’s hard to even imagine all the things that would have to change (from funding, to legislation, undoing all the embarrassing “teaching the controversy” curriculum, to say nothing of staffing) for a “non-technical solution.”
