Americans are worried about new technology. They are concerned that machines, including robots, will take over work now done by humans. These findings come from a new report by the Pew Research Center of Washington D.C. About 75 percent of Americans questioned by Pew said automation will increase income inequality between the rich and the middle class and poor. And 64 percent of people expect automation to be so common in America that people will face difficulty finding things to do with their lives. Some of the concerns about technology come from a distrust about whether machines will always make the right decision. Pew said many Americans believe humans have better judgement in dealing with complex matters -- or when there is not one clear answer.
