This discussion has been skirting very close to what I said in my AGIRI talk and book...
evolution invested massive computation in getting the KR right. Yes,the KR is built for (3+1)-D and a lot more-- it's not just a list of facts, or some database where you enter logical statements that are then processed by modus ponens or some such; it's procedures that can be invoked by code and guide when they should be and exploit the structure of the world in deep ways. Object permanence is not learned-- its essentially programmed. Yes, it requires sensory input to compile, but that's just the way it naturally evolved, because the genome programs chemical processes that take place in the brain, in the context of sensory inputs flowing through, and so naturally evolved to exploit them. Yes, general learning is always going to be inherently exponential, which is why we are not general intelligences. We are great at building on what we understand, which are the problems we already almost know how to solve, and happily include most of the problems we care about. But weak methods will not produce human-level results in any feasible amount of computation. A likely failure mode is inability to reproduce this underlying structure, because we don't have the resources evolution did, and its computationally hard and complex. Its not a given that we will fail-- but we have to recognize the problem and focus efforts, because success won't be easy.
