I read this story last year and really enjoyed it.

I knew that the Turing Test was supposed to be a way to test a machine’s intelligence. Not merely a way to determine whether a machine could simulate intelligence, but a way to determine whether the machine was genuinely thinking, understanding. The ‘intelligence test’ that Alan Turing proposed was a sort of ‘imitation game.’ In one room is an ordinary human; in the other is a machine (probably a computer). A human examiner, who does not know which room contains the machine, would engage in a natural language conversation with both participants. If the examiner is unable to reliably distinguish the machine from the human, then, according to Turing, we have established that the machine is thinking, understanding and, apparently, conscious.
