Online learning has been one of the most wonderful trends that bridged the gap between people of different languages. In third world countries, a lot of people make their living in online teaching, particularly in English. Koreans, Chinese, Japanese people are outsourcing their English studies to poorer countries like the Philippines. Its quite advantageous to some point though. It helps a lot when people are able to do many things at the same time and earn money in not just one job. I bet this trend will continue for decades and I quite think that the future of learning and education is through the internet.
