But then there are other areas of education where trying to divorce the subject from the teacher/student interaction is harmful. You can read history out of a book. I had a lot of history teachers that did exactly that. And replacing that with online education will be no better or no worse. But I also had history teachers that had passion for the source material (shit, I had a chemistry teacher with that sort of passion), and the "inspiration" that they provide is available in only that one specific way. It's not just liberal arts, even if it's mostly liberal arts. When you start getting into the nitty-gritty of biology (and I assume any deep subject, tbh), you NEED that sort of interaction in order for real education to happen.
