Now, what if we ask a robot to make the same decisions—what will it choose?

It’s a question that’s been cropping up more frequently as machines begin to tackle elaborate human tasks like driving. “It’s the most complex daily thing the average person does,” says Professor Raj Rajkumar of Carnegie Mellon University’s robotics department. According to Rajkumar, self-driving vehicles will be a multi-trillion dollar industry by the end of this decade—that’s a lot of robot trolleys zooming toward those five people.
