I think we're already at the start of the revolution in education he's asking for. With Google, Wikipedia and YouTube, if you want to know something, you can get that knowledge more effortlessly with each passing day. I think what's missing now is a rating system, a process guide to step you through it, and video conferencing to handle study groups, before we fully have a sort of Wiki-University.
I think the revolution he's talking about is one of more complex computer/human interaction. Writing programs, of one sort or another. Think Excel, or Emacs, or the Python repl.
It's hard to visualize what exponential growth means, but if you can simulate it using Python, you can suddenly imagine it.
