The essence of Turing's test is in the notion of INDISTINGUISHABILITY
by an observer. There is a machine in Glasgow that posts
from time to time some sequences of characters that succeed in fooling
me (even when I'm sober) so that I cannot distinguish it from a human
local-patriotic social-science-type :-{}. Such a machine passes the Turing
test. Maybe a stronger observer than myself (exponential, infinite) would
have caught this imposter.

Of course this is not "science" unless I augment it with statistical
"objective" gadgets.

BTW, Turing's test ideas had a lot of influence (so my crypto friends tell
me) on various notions in Cryptography and Complexity such as interactive
proofs and zero-knowledge protocols. But there you have to distinguish
between someone who knows some fact and someone who doesn't, or between
random and non-random, and not between intelligent and non-intelligent.
