The idea Jeff states above that the machines are just faking it seems to
me to be something Searle could believe.  Searle accepts the possibility
of a machine passing the Turing test.  But instead of being amazed at such
a feat Searle wants to say "Yes, but it's not really thinking it's just 
faking it".  This seems to me a somewhat strange egotistical? viewpoint.
I would be absolutely fascinated by a computer passing the TT.  

Searle accuses AI researchers of confusing simulation with reality.  To my
mind the line between the two becomes fuzzy at some point especially when
dealing with simulations of cognition.  Now I don't believe that any current
simulations even come close but if someone were to present me with what
they called a computer simulation that could pass the TT with me, I would
reply "You're no simulation!"

Yes, maybe it wouldn't be a simulation of "human" cognition but then I 
really wouldn't care if it could still pass the TT.

The Turing Test seems to me to be a perfectly valid test of thought/
understanding.  One person dismissed the TT on the grounds that understanding
is not just I/O behavior.  Yes but what else do we have to go on really.
Why do you suscribe intelligence/understanding to others?  Because of
their behavior.

If we were to have Searle perform the TT with a computer that could pass
it, Searle would accept that he was conversing with an intelligent
conscious agent until he found out it was a machine at which point he
would say, "Oh it's just faking it."
