Some experts think that corporations will eventually get into the business of higher education and bypass existing education structures altogether. Others predict there will be only a few physical universities left in the world come the middle of this century because technology will allow these institutions to reach students worldwide.
With no need for dorms, cafeterias, or libraries, infrastructure costs will be greatly reduced. There will also be a drastic reduction in the need for professors, who will in turn be better educated and better able to teach, especially when given sophisticated online and video learning tools to use in the classroom. A smaller infrastructure and lower personnel costs means a dramatic drop in cost - thus enabling more people to afford college, or so the theory goes.
