"We are approaching a time when machines will be able to outperform humans at almost any task," said Moshe Vardi, director of the Institute for Information Technology at Rice University in Texas.
"I believe that society needs to confront this question before it is upon us: If machines are capable of doing almost any work humans can do, what will humans do?" he asked at a panel discussion on artificial intelligence at the annual meeting of the American Association for the Advancement of Science.
Vardi said there will always be some need for human work in the future, but robot replacements could drastically change the landscape, with no profession safe, and men and women equally affected.
"Can the global economy adapt to greater than 50 percent unemployment?" he asked.
