Some of the most fascinating stories in science fiction center around artificial intelligence, or AI. One of the most famous examples is Data from Star Trek: The Next Generation, who also fulfilled the Pinocchio trope of being an android who wanted to be more human. Currently, an interesting AI is featured on CBS’ hit series Person of Interest. On it, “The Machine” -- actually an AI program lurking in cyberspace -- was originally programmed to ferret out terrorist activity before it happens.
