Deepfake Videos Are Getting Terrifyingly Real

Clip: Season 46 | 3m 36s

Deepfakes are an increasingly popular editing technique that uses artificial intelligence to alter faces and voices in videos. Part of the name comes from the AI used to create them, deep learning. Similar technology has been used in Hollywood for years, but with AI getting better and more accessible, today they’re all over the internet.
