Well, it's based on a bit of a philosophical cop-out, but basically anything that claims to be strong AI will always only be a philosophical zombie. It might behave intelligent, it might claim to be intelligent and conscious, but it's impossible to prove that it actually is intelligent and conscious, since it's impossible to objectively measure or describe consciousness.

In short, I'm with Searle. We can never have strong AI, but we can certainly have weak AI.
