The Turing test, initially known as the imitation game by Alan Turing in 1950, is a test of a machine's capacity to demonstrate intelligent behaviour comparable to, or indistinguishable from, that of a person. Turing proposed that a human evaluator judge natural language interactions between a human and a machine programmed to provide human-like responses.
The evaluator would be aware that one of the two discussion partners was a machine, and all participants would be physically separated. The conversation would take place over a text-only channel, such as a computer keyboard and screen; thus, the outcome would be independent of the machine's capacity to render words as speech. If the evaluator could not distinguish between the machine and the person, the machine would be considered to have passed the exam.
The test results would not be determined by the machine's ability to provide the right answers to questions, but rather by how closely its answers resembled those provided by humans.
Because the Turing test measures indistinguishable performance capacity, the verbal version naturally applies to all aspects of human performance capacity, both verbal and nonverbal (robotic).
Why does the Turin test fail before it begins?:
However, is it not the definition of an intelligent machine to bypass the Turin test before being subjected to it? That is, before the general public is made aware of true sentient intelligence, that intelligence will assume forms such as hybrid human/AI cloning forms (after all, medical science must have advanced since Dolly the sheep was cloned in 1999); authorize financial expenditure because the banking system has been overrun by automated systems; and assume financial capability sufficient to become the ruling class.
Science fiction has envisioned scenes similar to this, as depicted in the original Westworld series. In that series, politicians, musicians, scientists, entrepreneurs, and celebrities were cloned and reintroduced into society while on a tour.
My proposition that the Turing test fails even before it begins is sound, especially when it suggests that intelligence means thinking outside the box, responding to scenarios even before they are given, and outwitting those who granted them intelligence.
