Are you human or a machine? Prove it, by passing the Turing Test — a test of the ability of a machine to exhibit intelligent behavior.
In Alan Turing’s 1950 paper, Computing Machinery and Intelligence, the mathematician posed the question: “Can machines think?” But almost immediately he dismissed that question as too “meaningless” to be worthy of discussion, and swapped it for the much-more specific: “Are there imaginable digital computers which would do well in the imitation game?”
Turing’s original “imitation game” had nothing to do with artificial intelligence. It was a simple party game with three players — a man, a woman, and a judge of either sex. The judge sits in a room apart from the man and woman, and has to guess which is which from nothing but written communication.
The standard interpretation of the Turing Test today, however, replaces one of the participants with a machine which has to “imitate” intelligence. In this case, the judge has to decide which of the pair is the person, and which is the machine. The computer is successful, and passes the test, if — as Turing puts it — “the interrogator decide[s] wrongly as often when the game is played [with the computer] as he does when the game is played between a man and a woman."
