Are we doomed by The Great Stagnation?

Have we technophiles utterly deluded ourselves? Worse, instead of enjoying an Age of Innovation, are we actually stuck in a technological Dark Age? One that explains our stagnating living standards and general economic "disarray"? This is the possibility economist Tyler Cowen (George Mason, Marginal Rev, Mercatus) raises in The Great Stagnation, a pithy and provocative  new e-book essay. Here is my Forbes column on the topic: "Tyler Cowen's Techno Slump." I don't know how much I agree with Cowen, but I think he's given a big boost to an important conversation.
