AI Timeline: From Turing to ChatGPT The Dawn of Theoretical AI: Turing’s Imitation Game The conceptual foundation of artificial intelligence was laid not with a circuit board, but with a philosophical question: “Can machines think?” In his seminal 1950 paper, “Computing Machinery and Intelligence,” Alan Turing reframed this metaphysical question into a practical, empirically testable experiment he called “The Imitation Game,” now universally known as the Turing Test. The test posits that if a human interrogator, conversing via text with both a machine and a human, cannot reliably tell them apart, then the machine can be said to possess intelligence. This was a monumental shift, defining intelligence not by its internal processes (which we cannot observe in others anyway) but by its external, behavioral output. The Turing Test provided a clear, albeit controversial, goal for the fledgling field and ignited debates on the nature of consciousness, intelligence, and simulation that continue to this day. Crucially, Turing also described the concept of a “learning machine,” envisioning systems that could be educated like a child, a foreshadowing of the machine learning techniques that would dominate AI seven decades later.
