Perhaps you are seeing something that I am not. There are ~200 different types of "neurons", but no one seems to understand what the ~200 different things are that they have to do. Sure some simple nets are working, but I just don't see the expected "leap" from this. Computer hardware is improving as fast as any > field of technology has ever improved. We have already discussed here how architecture (of commercially available processors) has been in a state of arrested development for ~35 years, with ~10000:1 in performance just waiting to be collected.

My point was that some additional understanding, a wiring diagram, etc., would go a LONG way to getting over some of the "humps" that doubtless lie ahead. The history of AI is littered with those who have underestimated the problems.

(or just wait till 2015 and get one high-end PC). The point of agreement with BOTH of our various estimates is that computer horsepower is NOT a barrier. Figuring out the algorithms is the ONLY thing standing between us and AI. Back to those ~200 different types of neurons. There are probably some cute tricks buried down in their operation, and you probably need to figure out substantially all ~200 of those tricks to achieve human intelligence. If I were an investor, this would sure sound pretty scary to me without SOME sort of "insurance" like scanning capability, and maybe some simulations.
