WASHINGTON (WASHINGTON POST) - A new poll shows that in several countries around the world, large majorities of people believe it is most likely that robots will be doing much of the work done by humans within 50 years. The effects of this technological leap are not viewed optimistically by most, however. Instead, people largely say they think humans will struggle to find meaningful work and inequality will rise, the research found. The poll was conducted earlier this year by the Pew Research Centre in Greece, Japan, Canada, Argentina, Poland, Brazil, South Africa, Italy and Hungary. Pew also compared the responses in those countries to a poll done in the United States in 2015 that asked about automation.
