I'm not saying remove the human element entirely, but there's a lot of low hanging fruit in education to consider where technological automation can help improve the productivity of educators.This x1000. With all the improvement in educational technology, it's weird that the gold standard of elite education apparently remains the lecture.
I am reminded of the quote: College is a place where a professor’s lecture notes go straight to the students’ lecture notes, without passing through the brains of either.
Part of the issue is that college-as-elite-networking-venue needs to remain scarce, by definition, if it is to retain its value. If everyone can "go to Harvard" (through online delivery, enhanced ed-tech, automation, etc) then the scarcity is lessened. When you go to an elite college, you don't just get an education, you get association with a brand that, you hope, retains and increases in value.
