Abundance; great book that's insanely optimistic about the future. Sure it cherrypicks the "what went well" part of our history, but a lot more has went well compared to a couple of failing industries.. http://www.amazon.com/Abundance-Future-Better-Than-Think/dp/...
I've enjoyed Abundance by Peter Diamandis, CEO of the X-Prize foundation. It's by no means laden down with details, but it is an entertaining overview of emerging technologies and how they might be put to use.
