Very interesting talk. I'd love for him to write a history of capitalism type book. "The History of Innovation and Globalization". Start it off with the x-axis=globalization and y-axis=innovation model and go from say 18th century to now. I always enjoy history of economics books. I like the mainstream books but really enjoyed the perspective and research that went into "An Austrian Perspective on the History of Economic Thought". I am not aware of any good history type books from a more pragmatic business oriented point of view. Thiel has some interesting insights and perspectives.

Unfortunately that book probably wouldn't be a good use of his time but come on Peter, I know you want to write it :)
