Can machines think?
(viewers are encouraged to compete). To give the machine and humans equal opportunity, four basic statements are given which words are replaced by letters. For example, “a lion is a predator” becomes “a L is a P”. After reading the statements, the machine is asked to deduce. Then, it is asked to imagine rationally. Finally, a lie is given which the machine detects as false, because it would contradict everything it has learned and reasoned so far. At the video’s end, the letters are turned back into their original words.
