I don't necessarily disagree with your point, but Western societies are already plagued by loneliness and isolation. That will only get worse if everyone just stays at home to learn. The point of schools -- I mean, less for adult education, but still -- has always been not just the concrete knowledge being taught, but also social skills, patience, humility, learning how to learn, and interaction with other humans.
If we want an education system optimised for producing capable agent jockeys, then by all means this seems an efficient way to do so. But sometimes I wonder if, for all the modern wonders capitalism and individualism have brought us, we haven't lost track of being humans - all sharing a temporary seat on a fragile spaceship, hurtling through darkness and uncertainty.
Just keeping our heads to the AI grindstone until we die doesn't really seem to be a good answer to what to do with our existence.
