Will change really happen this time?

This short animation of a talk by Sir Ken Robinson does a fairly good encapsulation of the challenges of K-12 education. What's interesting to me is that, for many years people who believed this way mostly spoke and wrote books for, well... each other. Today these discussions are taking place in policy circles. And the tools for structural change (especially customization) are there. Many voices are saying the time has finally arrived for the "complete retool" we've all discussed for decades.  Has it?
