The “Turing test” assesses a machine's ability to exhibit human-like intelligence. Proposed by Alan Turing, the test evaluates whether a machine can engage in conversation indistinguishable from that of a human. If a human evaluator cannot reliably tell the machine from a human based on responses, the machine is considered to have passed the test. This concept is foundational in the field of artificial intelligence, as it questions the nature of thinking and consciousness.
