"College product" is overpriced and is largely sustained by "parent pressure". Parents and society in general do not know yet any acceptable/established alternatives.

My bet is on "open horizontal stack". Right now, every college is a small "vertical stack": its own library, teachers, physical space, etc. I think in the future we will have one national library (e.g. Chegg.com), one network of educational spaces, one network of classes (e.g. SupercoolSchool.com), one employment system for students, one office for transfer of technology, etc.
