Alan TuringAlan Turing — mathematician who defined computability, broke Enigma, and posed the imitation game.'s October 1950 Mind paper asked whether machines can think and proposed the imitation gameTuring's conversational test for machine intelligence — if replies match a human, capability matters more than definition. — now called the Turing testAlan Turing's criterion for machine intelligence — can a computer convincingly imitate a human in conversation?.

Why it mattered
It gave researchers a concrete experiment instead of endless definitions of 'thinking.'
What it solved
