“I propose to consider the question, ‘Can machines think?’”
FIRST EDITION IN ORIGINAL WRAPPERS of Alan Turing’s landmark explanation of what would become known as the “Turing test” to determine whether a machine can ‘think’.
In “Computing Machinery and Intelligence,” “Turing sidestepped the debate about exactly how to define thinking by means of a very practical, albeit subjective, test: if a computer acts, reacts, and interacts like a sentient being, then call it sentient. To avoid prejudicial rejection of evidence of machine intelligence, Turing suggested the ‘imitation game,’ now known as the Turing test: a remote human interrogator, within a fixed time frame, must distinguish between a computer and a human subject based on their replies to various questions posed by the interrogator. By means of a series of such tests, a computer's success at ‘thinking’ can be measured by its probability of being misidentified as the human subject. Turing predicted that by the year 2000 a computer ‘would be able to play the imitation game so well that an average interrogator will not have more than a 70-percent chance of making the right identification (machine or human) after five minutes of questioning.’ No computer has come close to this standard” (Britannica). Along with Turing’s own 1936 paper “On Computable Numbers,” “Computing Machinery and Intelligence” is regarded as one of the foundational works on artificial intelligence.
