Peer pressure and the desire to surpass your heroes seem like a large part of why teachers and other students are so important however. If at some point a teaching simulator of this caliber is created, we could integrate a ranking system where you are automatically connected with people at a similar level to compete, and you can level up by helping people with problems as well (To continue the idea of gamification to its logical extreme...) The systems which let people learn in competetive games like starcraft are amazing, and if they were properly applied to useful education at least some people would benefit tremendously.
