When the Director of Research for Google compares one of the most highly regarded linguists of all time to Bill O’Reilly, you know it is on. Recently, Peter Norvig, Google’s Director of Research and co-author of the most popular artificial intelligence textbook in the world, wrote a webpage extensively criticizing Noam Chomsky, arguably the most influential linguist in the world. Their disagreement points to a revolution in artificial intelligence that, like many revolutions, threatens to destroy as much as it improves. Chomsky, one of the old guard, wishes for an elegant theory of intelligence and language that looks past human fallibility to try to see simple structure underneath. Norvig, meanwhile, represents the new philosophy: truth by statistics, and simplicity be damned. Disillusioned with simple models, or even Chomsky’s relatively complex models, Norvig has of late been arguing that with enough data, attempting to fit any simple model at all is pointless. The disagreement between the two men points to how the rise of the Internet poses the same challenge to artificial intelligence that it has to human intelligence: why learn anything when you can look it up?
