> Our current theoretical understanding of how human cognition arises from neural processes is probably close to a level sufficient to build human level AI. No. Not even remotely close. If that were true we'd be able to emulate the behavior somewhat of simpler organisms that don't have the connectivity of a human brain. The fact of the matter is, we simply don't understand cognition. I'd say the challenge in realizing strong AI right now is both a lack of understanding of the brain as well as emulating its mode of computation, which is different from a traditional digital computer.
