If you want to see the future of online education, lots of people will tell you to head out to Silicon Valley or New York City or Cambridge (either of them) or London -- or to some other ('highly developed') place that tends to be written about by the (English-speaking) press. Fair enough: You can find lots of cool stuff going on in such locations.
I tend to think that it can be even more interesting to talk with local groups and people exploring 'innovation at the edges', especially those who are trying to solve educational challenges in places outside of the 'highly developed industrialized economies' of North America and Europe, Australia and Japan. If you believe that some of the most interesting innovations emerge at the edges, talking with NGOs, start-ups and companies in places like Nairobi or Cape Town, Mumbai or Bangalore, Jakarta or Karachi, who are trying to address educational needs, contexts and challenges of a different nature and magnitude than one finds in, say, Germany or Canada or Korea, can be pretty eye-opening. Observing what is happening in 'developing countries' -- where, after all, most of the world lives -- can provide a quite different perspective on what the 'future of education' might look like. This is especially the case in places where people are not trying to port over educational applications, content and experiences developed e.g. for desktop PCs and laptops, but are rather pursuing a mobile first approach to the use of technologies in education.
If you want to get a glimpse of what the (or at least "a") future of online education might look like in much of the world, you might want to direct your gaze to consider what's happening in a place that combines attributes from, and shares challenges with, education systems in both 'highly developed' and 'less developed' countries, somewhere with a significant urban population as well as large populations in rural areas. A place, in other words, like ... China.
