Can AI stamp out fake news?

During the recent U.S. Presidential election, it became clear that both the left and right were using the Internet and social media to disseminate false information using a new form of insidious propaganda: "fake news." Nearly in real-time and at little cost to the campaigns, organizations and individuals were able to post fake news stories on news sites, social media, and blogs that looked and felt legitimate. Millions of people saw these stories and may have been influenced by what they read. "If we are not serious about facts and what's true and what's not -- and particularly in an age of social media where so many people are getting their information in sound bites and snippets off their phones -- if we can't discriminate between serious arguments and propaganda, then we have problems." It's still up for debate whether fake news changed the outcome of the recent presidential election, but most would agree the country is better off if we were reading accurate stories.
