“In the darker corners of the Internet, you can now find celebrities like Emma Watson and Selma Hayek performing in pornographic videos. The clips are fake, of course—but it’s distressingly hard to tell. Recent improvements in artificial intelligence software have made it surprisingly easy to graft the heads of stars, and ordinary women, to the bodies of X-rated actresses to create realistic videos.

These explicit movies are just one strain of so-called “deepfakes,” which are clips that have been doctored so well they look real. Their arrival poses a threat to democracy; mischief makers can, and already have, used them to spread fake news. But another great danger of deepfakes is their use as a tool to harass and humiliate women.”
