All three AI experts agreed that ethical considerations must be at the forefront of research. "One thing I'm seeing among my own faculty is the realization that we, technologists, computer scientists, engineers who are building AI, have to appeal to someone else to create these programs," said Moore. When coming up with a driverless car, for example, how does the car decide what to do when an animal comes into the road? When you write the code, he said, there's the question: how much is an animal's life worth next to a human's life? "Is one human life worth the lives of a billion domestic cats? A million? A thousand? I would hate to be the person writing that code."
