The problem of AI is that it has much more complexity than we used to think. Even best guys like Minsky have grossly underestimated the complexity, so they got stuck, and now are in a process of developing more subtle, refined theories. In some sense the story of modern AI is a story of how Minsky assigned to figure scene decomposition for robotic vision as a summer project, and now teaching Society of mind and calling for entirely different approach to what is intelligence. It is not, of course, some massively parallel recursive problem solver implemented in neurons, it is too naive view, so there is no use to search for one.) It is as complicated as actions of whole humanity with a billions of semiindependent agents.
