Problem is there are two AIs - strong and weak. Weak AI is just about replicating stuff humans can do - chess playing, diagnosis, vison, talking etc. Strong AI is all about building something that thinks and is consious - like a human. Weak AI never dies - strong AI goes through cycles as it hits a high and then a low. See:
