the Turing test (are we talking about the imitation game?) is an attempt to make an operational definition of consciousness. I personally think it is a lousy concept, except that it is better than anything else we have. Interestingly, there are lots of people who would fail the imitation game, or at least get voted off the island in competition with some current AI programs. Actually it's already happened. Some years back there was an expo in which computer programs were set up in a chat room with an equal number of real people. One woman was voted to be a 'bot, because she knew too much.
But were any 'bots voted to be humans?
