Furthermore, the fact that some people use in-person tutors doesn't mean that no one uses remote tutors. This absolutely happens. We live near Stanford, and there are tons of Stanford students who advertise their tutoring services on ND. These kids didn't go to local schools, and they don't know the local curriculum — they're from all over. But parents pay to have smart students tutor their kids.
I imagine that these parents would also pay to have an AI bot tutor their students if the results were good, the price were favorable, and the bot were (of course) available 24/7.
BTW, I'm curious where you live that "education technology" is called "edutech". You mention having been in the field a long time, but I've never heard it called this (always "edtech"). Where have I not been that it has this alternate moniker?
