Artificial intelligence may replace as many as 4 million, or 14% of South Korea’s jobs, over the next two decades, a central bank study said, adding to a chorus of warnings on the looming disruption to labor markets around the world.

Chemists, doctors, lawyers, accountants and asset managers are among the most threatened, while people in religious fields, food services, teaching and singing are the least vulnerable, they said Thursday.
