The Critics – Books– Your Lying Eyes

People now use A.I. to generate fake videos indistinguishable from real ones. How much does it matter?

The computer scientists Walter J. Scheirer argues that our political fears about the use of deceptive deepfakes are misplaced.

“There’s a video of Gal Gadot having sex with her stepbrother on the internet.” With that sentence, written by the journalist Samantha Cole for the tech site Motherboard in December, 2017, a queasy new chapter in our cultural history opened. A programmer calling himself “deepfakes” told Cole that he’d used artificial intelligence to insert Gadot’s face into a pornographic video. And he’d made others: clips altered to feature Aubrey Plaza, Scarlett Johansson, Maisie Williams, and Taylor Swift.

Porn, as a Times headline once proclaimed, is the “low-slung engine of progress.” It can be credited with the rapid spread of VCRs, cable, and the Internet—and with several important Web technologies. Would deepfakes, as the manipulated videos came to be known, be pornographers’ next technological gift to the world? Months after Cole’s article, a clip appeared online of Barack Obama calling Donald Trump “a total and complete dipshit.” At the end of the video, the trick was revealed. It was the comedian Jordan Peele’s voice; A.I. had been used to turn Obama into a digital puppet.

The implications, to those paying attention, were horrifying. Such videos heralded the “coming infocalypse,” as Nina Schick, an A.I. expert, warned, or the “collapse of reality,” as Franklin Foer wrote in
