This is a long video but worth listening to IMO. I've put it at a point where you might get a sense of the state of the game in AI. Prof Furber is one of the creators of the ARM instruction set that's powering all your phones and he is now working on a project that has built a neuromorphic computer at Manchester University which has 1 million processors with an architecture that's designed for emulating spiking neural networks.
Elsewhere in the video you'll hear how a room--sized machine could now emulate a mouse brain if we knew enough about how it works to create a model.
This is not to be down on AI at all but I feel that those of us outside the field might not have a very good idea of the difficulty of the challenge.
