When Bill Gates and Mark Zuckerberg sound the same dire warning about jobs, it's time to listen

Some 38% of jobs in the U.S. are at "high risk" of being replaced by robots and artificial intelligence over the next 15 years, a separate estimate by consulting and accounting firm PwC found, which is still lower than Germany (35%) and the U.K. (30%). They include composers and artists, nurse practitioners, home health aides, elder care specialists, child care workers, engineers, teachers and, finally, human resources executives, a report released earlier this month by careers firm Challenger, Gray & Christmas concluded. As MarketWatch previously reported, there's an 83% chance that automation will replace a job that pays $20 per hour, according to a White House report released last year. Traditional energy and energy efficiency sectors employ around 6.4 million Americans, according to the 2017 U.S. Energy and Employment Report.
