The era of having numerous nation-states is coming to an end; but what will replace them?

So will we end up with few huge tyrannical mega-states (like China, Russia, USA), bumbling nanny states (EU, Canada, Oz) or violent chaotic but largely free anarchist groupings (Somalia, Afghanistan, Mexico)? Good question and one that this article in New Geography speculates upon. The author maintains that the cultural elite leadership class for such global entities is in place now and is largely in control already. Now if only those ignorant yahoos who inhabit the world would just stop clinging to their guns and religion and let them run things their way it would all be good. Sheesh.
