Even the first year or two of any undergrad stem education (math, physics, chem, etc) could be done through Khan Academy right now. Set up a test-out system where you study on your own at home and save the $$$, eliminate gen-Ed, and boom you’re down to 2 years of paid tuition. It would be very easy to get the last two years of any engineering curriculum on Khan Academy too...

The class lecture setting is incredibly archaic, expensive, and inefficient. It still exists to promote a fake priesthood where professors and administrators are our betters and we are supposed to kiss their asses and worship them.
