Argument anticipated by Jack Copeland, 1993.
"This objection commences with the observation that a simulated X is not an X. Simulated diamonds are not diamonds. A simulated X is X-like, but is not the real McCoy. Now, suppose a computer passes the Turing Test. How could this possibly show that the computer thinks? Success in the Test shows only that the computer has given a good simulation of a thinking thing" (Copeland, 1993, p. 46).
