I think online education is under-utilizing the scale of the internet for course creation. With Stanford, Harvard, and MIT putting classes online, you just have a handful of professors giving lectures to a much bigger audience. But there are millions of professors around the world, and if just the top 1% all put their courses online, we'd have more styles of presenting the same material so students could pick the one that suits them. Imagine being able to take that game theory course but choose a Stanford professor, or a professor from a small college in the Midwest, or a superstar from IIT in India. Or being able to select a professor with a more academic tone, or a comedic tone, or one who uses sports analogies. This is where I think the real power of online learning is.
