An MIT graduate student has used game theory to prove that the Nash equilibrium of complex games belong to problems of PPAD complexity, which is a subset of FNP problems which is a subset of NP problems. Somehow this all leads to the obvious conclusion that, if you can generalize a solution to poker, you can discover the Nash equilibrium of the national economy. The only person in the world I know that any of this would make sense to is now nodding his head sagely, and coming up a with a reply that'll just make my head explode a second time.
