When I discussed deepfakes in an earlier column, I conceptualized their uses as primarily associated with video: Videos made with artificial intelligence that purported to show people doing and saying things they had never done or said. I posited the upcoming election cycle and videos purporting to provide evidence of criminal conduct as particular areas for mischief: Pictures worth far less than a thousand words. But as with so much emerging technology, uses evolve. The recent documentary of Anthony Bourdain's life and suicide, "Roadrunner", includes three audio clips purporting to be Bourdain speaking, but that are in fact made using artificial intelligence. Audio deepfakes. Deepfakes allow us to make the dead speak, or at least to imitate them doing so.
