I think we need a common online learning platform for K-12. That at least gives everyone the same access to the best lecturers, independent of the low education budgets from poorer areas, as well as e.g. AP classes that they can't get locally. It reduces the need for "redundant" teachers there just to deliver a mediocre lecture. Teachers are still needed to provide individual help, something that doesn't scale as easily as online lectures. That could be done locally or remotely. Students need a computer and internet access. Providing them with that is cheaper than trying to fund local teachers and buildings, though. Then we need some way to provide the social aspects provided by schools, sports, chemistry labs, as well as all the other services like food and counseling which are not part of education but are provided by the school system. The same thing applies to the university system. I think this is the way out of the current cost explosion/bubble.
