This is a brilliant synopsis of the state of the art -- truly fantastic -- and yet the presentation concludes with, "The innovation won't happen because I can't see where it will come from," and that's not entirely fair. Some areas he covers aren't exhaustively covered and what's missing is quite interesting. In other words, cheer up, there's more hope than what's shown here.
I think this is just a fustration with how little direct incentive there is from our economic system to fix the problem. The only chance of this paradigm existing is as a long shot project that is gifted to society, and the person that makes this gift has the slim chance that it doesn't succeed and all the effort is wasted.
