When is a Computer Said to Have Passed A Turing Test

A computer is said to have passed the Turing test "if it is able to convince a human evaluator that it is a human, based on its responses to a series of questions or prompts." The Turing test, which was first proposed by the mathematician and computer scientist Alan Turing in 1950, is designed to test a machine's ability to exhibit intelligent behavior equivalent to, or indistinguishable from, that of a human.

In the Turing test, the computer must engage in natural language conversations with one or more human evaluators, who are unaware that they are communicating with a machine. If the evaluator(s) cannot consistently distinguish the computer's responses from those of a human, the computer is said to have passed the Turing test.

It is worth noting that passing the Turing test is not equivalent to demonstrating true intelligence, consciousness, or sentience, as it only tests a machine's ability to mimic human behavior. Nevertheless, passing the Turing test has historically been considered a significant milestone in the development of artificial intelligence.
