Some law firms now use artificial intelligence software to scan and read mountains of legal documents, work that previously was performed by highly-paid human lawyers.“Robots continue to have an impact on blue-collar jobs, and white-collar jobs are under attack by microprocessors,” says economics professor Edward Leamer.

It’s that they’re better. “In some cases the quality requirements are so exacting that even if you wanted to have a human do the job, you couldn’t,” Burnstein says.Same goes for surgeons, who’re using robotic systems to perform an ever-gr...
