A computer science class didn't notice one of its TAs was a chatbot

The Turing test has always been an approximate benchmark for good AI. In the test, a human is supposed to converse with a machine over text for five minutes; if the human doesn't realize that they are talking to a machine, then the computer passes as AI "indistinguishable" from human intelligence. DON'T MISS: To make the iPhone exciting again, Apple has to launch... an Android phone? Earlier this year, Georgia Tech professor Ashok Goel noticed he was spread thin for teaching assistants for his computer science course. So Goel programmed IBM's Watson system to work as an online chatbot, answering some of the 10,000 online questions submitted by students during the course.
