It's not at all clear to me that Khan Academy is really "disrupting education". They may be awesome and all, but when an industry is disrupted something more fundamental is at work -- other businesses are displaced and shut down, people lose their jobs, and billion-dollar market segments get turned into million-dollar market segments (or eliminated completely). To compare, look at what's happening in the music or book industries right now. It's hard to find a retailer that sells CDs today because that business has been disrupted. It's far from clear to me that KA is actually having that "disruptive" effect, or that they will be able to do that in the future.
