That is actually something many have probably not thought of - if elementary school, middle school and high school was no longer taught in classrooms, where would all the kids go for 8 hours a day and how would parents be able to deal with them? It would require a two parent system where one parent works and the other stays home all day - and an education system that requires this, at least in our times, would simply not be tolerated at all.
If the primary goal of classrooms is to teach not just the material but also genuine problem solving skills and how to think for oneself and to teach all the skills needed to be employable, could online teaching replace that entirely in the near or distant future?
Online teaching and homeschool groups could.

Then all those people can day sit all the kids no longer going to school, or be at home for their own kids!
