“He proposed an imitation game. There would be a man (A), a woman (B) and an interrogator (C) in a separate room, reading the written answers from the others, trying to work out which was the woman. B would be trying to hinder the process. Now, said Turing, imagine that A was replaced by a computer. Could the interrogator tell whether they were talking to a machine or not after five minutes of questioning? He gave snatches of written conversation to show how difficult the Turing Test would be: Q: Please write me a sonnet on the subject of the Forth Bridge. A: Count me out on this one. I never could write poetry. To imitate that a computer would need deep knowledge of social mores and the use of language. To pass the Turing Test the computer would have to do more than imitate. It would have to be a learning entity.”
