This Is What a True Artificial Intelligence Really Is

To borrow a cliché opening from the last high school commencement or Maid of Honor speech you heard, the dictionary defines artificial I\intelligence (AI) as 1: a branch of computer science dealing with the simulation of intelligent behavior in computers; and 2: the capability of a machine to imitate intelligent human behavior. But, do these definitions really explain the difference between an artificially intelligent system and one that's just programmed to be useful? What is "intelligent" behavior or, more specifically, "intelligent human behavior"? The definition is clearly open to some level of interpretation. Combine that ambiguity with the term's cool sci-fi connotations, and you get a world in which, as The Atlantic's Ian Bogost puts it, "deflationary examples of AI are everywhere."
