Summary: The issue for strong AI is whether it is possible to have a human-like mind without having a human-like body.

In the original Turing Test, it was required that the interrogator only be able to question the "contestant" via a teletype system, not in "person". The reason for this stipulation is that the goal of artificial intelligence is to reproduce a human mind, *not* a human body. It isn't fair, then, to look at the contestant and say "Hey, I can tell you are a computer by your keyboard!" Likewise, I think it is not fair in the Chinese Room to test the veracity of answers like "What color tie are you wearing?". If Searle keeps inside the Chinese Room, then the interrogator wouldn't be able to know that the answer is false. Answering *correctly* is not required for the Turing Test, only answering convincingly. Someone in this newsgroup (I don't remember who) brought up the issue that if computer program succeeded in passing the Turing Test, it would have to do so through lying; it would have to claim to be a human being, to have headaches occasionally, to wear green ties, etc. I don't think the fact that these claims are false should in any way be held against the computer program; it could very well have the *mind* of a human being with stomach aches, etc., and so could be answering truthfully as far as it knows. A human being can be similarly mistaken about the state of his or her own body; for example, the "phantom limb" experience of amputees, or the "phantom odors" experienced when one's brain is stimulated by an electrode.
