I am certain a world full of autodidacts would supersed the university system we see today. For these autodidacts the universe might truly become a "University of Life". I am also certain that the true barriers keeping most people from becoming autodidacts are not financial or social but rather built by the schooling system into our minds. This schooling system itself was probably setup to create obedient soldiers and weapons technicians so as to win wars. Can someone please queue Pink Floyd's "Another Brick In The Wall" [1]?
That barriers are "built by the schooling system into our minds" is exactly what I meant by my "social barriers". Sorry for not being clearer, we agree on that point. I still think there are very real financial barriers to education, perhaps not for the true autodidacts who can learn everything from a book, but for everyone else who requires some structured instruction.
