Over 5 million jobs will be lost by 2020 as a result of developments in genetics, artificial intelligence, robotics and other technological change, according to World Economic Forum research.

About 7 million jobs will be lost and 2 million gained as a result of technological change in 15 major developed and emerging economies, WEF founder Klaus Schwab and managing board member Richard Samans said in "The Future of Jobs." The findings are taken from a survey of 15 economies covering about 1.9 billion workers, or about 65 percent of the world's total workforce.

It's already a hot topic thanks in part to books such as "The Second Machine Age" and "The Rise of The Robots," while Bank of England Chief Economist Andy Haldane has warned that the millions of jobs at risk from automation are creating issues officials need to address.
