John Evans on 27 Feb 18"FEBRUARY 22, 2018 -From the instant replay that decides a game to the bodycam footage that clinches a conviction, people tend to trust video evidence as an arbiter of truth. But that faith could soon become quaint, as machine learning is enabling ordinary users to create fabricated videos of just about anyone doing just about anything. Earlier this month, the popular online forum Reddit shut down r/deepfakes, a subreddit discussion board devoted to using open-source machine-learning tools to insert famous faces into pornographic videos. Observers say this episode represents just one of the many ways that the this technology could fuel social problems, particularly in an age of political polarization. Combating the negative effects of fabricated video will require a shift among both news outlets and news consumers, say experts. "Misinformation has been prevalent in our politics historically," says Brendan Nyhan, a political scientist at Dartmouth College in Hanover, N.H., who specializes in political misperceptions. "But it is true that technology can facilitate new forms of rumors and other kinds of misinformation and help them spread more rapidly than ever before." So-called fake news has been around long before Macedonian teenagers began enriching themselves by feeding false stories to social media users. In 1782, Benjamin Franklin printed a falsified supplement to the Boston Independent Chronicle maligning Seneca Indians in an attempt to influence public opinion during peace negotiations with Britain."
