There are three basic ingredients of the Khan–College Board revolution: (1) More will be on you, and you’d better take ownership of that fact and seek out intelligent assistants and assistance everywhere that you can; (2) precisely because more is on you, government and social organizations need to get serious about providing you not just any tools, but much better tools—informed by artificial intelligence tailored exactly for you and your needs and reinforced by a caring adult or coach, wherever possible; and (3) technology can take you only so far. Concentration also matters.
