Some combination of: 1. A tinkering mentality a la DIY as educational institutions fail to keep up with accelerating progress; as developing world grows more important on the world stage; and as kids in the affluent world get bored. 2. Machine learning turning into machine teaching, like Google Now but for retention and discovery, with aspects of Duolingo, Khan Academy, probably with social gamification and sharing ("Billy just learned these basic facts about accounting!") 3. Digital economy acceleration, probably with blockchain tokens, leading to a huge incentivization of people to produce their own educational material, mentor others, etc. Imagine a bunch of creative people making videos and stuff, in global efficient competition, and being directly rewarded for upvotes/views with tokens, maybe even community-specific tokens with different exchange rates to other communities (see Steemit for a glimpse of this).
