I think I found it: edtech. Edtech is a notoriously hard one to crack, and it's a long game. Fortunately I've always enjoyed working with children and philosophising about the best ways to teach and learn. The bad news: most edtech are flops.
Still, it adds a bit of meaning to the everyday hum-drum.
Also, an efficient, nationwide online schooling system (CAVA in California as an example,) would be the end of something like 90% of the teachers in the country. Would that be a good thing or a bad thing? Who even knows...
Everything has trade-offs.
So that at least frees me from that glum thought of IQ vs Nurture tug-o-war.
While I'm at it, I might as well advertise:

Someone with good tech skills will especially be welcomed, as I'm a bit rusty, and plus it's more enjoyable to make pictures and courses. I'm based in the UK but I'm not fussy about having an online collaborator :)

Not saying that teacher jobs are likely to increase, just that I'm not sure they'd go away altogether, either.
