Google's AI passed a famous test -- and showed how the test is broken

In 1950, the ingenious computer scientist Alan Turing proposed a thought experiment he called the Imitation Game. An interviewer converses via typewriter with two subjects, knowing one is human and the other a machine. If a machine could consistently fool the interviewer into believing it was the human, Turing suggested, we might speak of it as capable of something like thinking. Whether machines could actually think, Turing believed, was a question "too meaningless to deserve discussion." Nonetheless, the "Turing test" became a benchmark for machine intelligence.
