Robot race: These three countries are winning

When it comes to making machines to perform tasks that humans have done for years, the United States, China and India are far ahead of anyone else, according to a top tech industry executive. The three countries are leading an artificial intelligence (AI) revolution, Malcolm Frank, head of strategy at leading outsourcing firm Cognizant, told CNNMoney in an interview. Frank is the co-author of a recent book entitled "What to Do When Machines Do Everything," on the impact artificial intelligence will have on the global economy in the coming years. "I think it's three horses in the race, and that's probably the wrong metaphor because they are all going to win," he said. "They are just going to win differently."
