I think it’s trending to a mixed learning environment–some online, some in class. In 20 years technology will be so mobile that “online education” could well be completely “mobile education”. Or maybe Google glasses will be the ultimate teacher 🙂

According to a Sloan Consortium survey “Sixty-five percent of higher education institutions say that online learning is a critical part of their long-term strategy,” http://sloanconsortium.org/publications/survey/going_distance_2011. So apparently, a lot of higher ed institutions are already planning on implementing it more.

I agree with @Muvaffak, that MOOCs won’t last unless they provide accredited degrees. Employers won’t accept a certification from some random online website.
