hot take: if all models stopped improving today, we could get there with today's technology.
No, you couldn't whip out a foundational model out of the box to do this, but we could likely engineer our way to guardrails to support this without substantial hallucinations (i.e. fewer than the 95th percentile of human teachers.)
Also in no way would this replace everything teachers do. I'm talking purely academic curiosity.
>I'm talking purely academic curiosity.
Sure. In that lens, anything is possible. We put people on the moon with tech less powerful than a modern graphing calculator.
Reality, however, is disappointing and not actually incentivized by bettering humanity.
