Artificial Intelligence and What Computers Still Don’t Understand

Gary Marcus in The New Yorker:

Marcus-turing-test-580Hector Levesque thinks his computer is stupid—and that yours is, too. Siri and Google’s voice searches may be able to understand canned sentences like “What movies are showing near me at seven o’clock?,” but what about questions—“Can an alligator run the hundred-metre hurdles?”—that nobody has heard before? Any ordinary adult can figure that one out. (No. Alligators can’t hurdle.) But if you type the question into Google, you get information about Florida Gators track and field. Other search engines, like Wolfram Alpha, can’t answer the question, either. Watson, the computer system that won “Jeopardy!,” likely wouldn’t do much better.

In a terrific paper just presented at the premier international conference on artificial intelligence, Levesque, a University of Toronto computer scientist who studies these questions, has taken just about everyone in the field of A.I. to task. He argues that his colleagues have forgotten about the “intelligence” part of artificial intelligence.

Levesque starts with a critique of Alan Turing’s famous “Turing test,” in which a human, through a question-and-answer session, tries to distinguish machines from people. You’d think that if a machine could pass the test, we could safely conclude that the machine was intelligent. But Levesque argues that the Turing test is almost meaningless, because it is far too easy to game.
