"Deepfakes seem to tap into a really visceral part of people's minds," Henry Ajder, a UK-based deepfakes expert, told Insider. "When you watch that Tom Cruise deepfake, you don't need an analogy because you're seeing it with your own two eyes and you're being kind of fooled even though you know it's not real," he said. "Being fooled is a very intimate experience. And if someone is fooled by a deepfake, it makes them sit up and pay attention." The good news: it's really hard to make such a convincing deepfake. It took Ume two months to train the AI-powered tool that generated the deepfakes, 24 hours to edit each minute-long video, and a talented human impersonator to mimic the hair, body shape, mannerisms, and voice, according to The New York Times.
