The unfortunate reality is that a lot of success boils down to IQ (and some other metrics of mental acuity,) which is mostly hereditary or imprinted, so that's depressing for a lot of people in education who started off wide-eyed and optimistic.
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...
Hmm my edtech aims for global literacy; so a reading programme for ESL kids who may be disadvantaged enough to only have access to a smartphone.
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 :)

Everything has trade-offs.
