"A machine with superhuman intelligence is a staple of science fiction. But what about a machine with just ordinary human intelligence? A machine that's so human-like in its behavior that you can't tell if it's a computer acting like a human, or a real human?
That's what a Turing Test is designed to explore. The test is named for the British computer scientist Alan Turing, who first proposed it. (He's the guy the movie The Imitation Game was about.) Essentially, it involves making a program that does something a human might do — in a way that's indistinguishable from what an actual human would produce."
