There won't be any policy-driven change in the education system of the kind that TED speakers would love to see.

The system won't change meaningfully until the world around it changes first. That is to say, until private sector alternatives/supplements start making an impact in education without the help of the state. But that's entirely possible.

The issue is that nobody has really built anything all that special for the education sector yet. The best we have are MOOCs, which are, for all their production values, just static resources and not a new way for a child to learn.
