With how expensive it is to go to college for students, and with how expensive it is to pay faculty at colleges, combine that with the amount of money it cost to maintain a college's upkeep,
I think in the very near future the actual act of going to college via a college campus, going to lecture hall, etc. will be extinct. With the advent of social media sites such as YouTube, it makes teaching incredibly easier and much cheaper. I can imagine it now, a college's psychology department will be exclusively via all of the professor's channels on YouTube and you would need a code to access the lecture on your computer. Online courses and things like this are already happening as we know, but I feel that in the very near future schools are going to be teaching their entire department(s) through sites like YouTube.
Compare how much it would cost for a student to attend __________'s sociology program. Then compare how much it would cost if that class was online only, and the lectures and test, etc. were all given through his YouTube, Twitter, and his instagram? Sure, these money hungry administrators would try and come up with a way to charge students, but I can't imagine that the cost of going to college with this method wouldn't be much smaller.
