Recent advancements in machine learning have got Farid particularly worried. 2017 was a bumper year for image-faking technology. In July, researchers at the University of Washington trained an AI that converts audio into realistic mouth movements,
creating a video of someone saying words they never actually uttered. A paper from the graphics card company Nvidia released in October showed that you can use machine learning to automatically change the weather in a photograph, turning a summer’s day into a wintery scene with snow piled up on pavements and the trees leafless.
