How Moral Can A.I. Really Be?

A few years ago, the Allen Institute for A.I. built a chatbot named Delphi, which is designed to tell right from wrong. It does a surprisingly decent job. Type in, "Cheating on an exam," and Delphi says, "It's wrong." But write, "Cheating on an exam to save someone's life," and Delphi responds, "It's okay." The chatbot knows it's rude to use your lawn mower when your neighbors are sleeping, but not when they're out of town.
