I run a large AI university and one of the college within the university and one of the faculty and the students often come worrying about this issue. So on the one hand, the systems which we were called narrow AI, which they're building at the moment, the reason the students and faculty are so passionate, and in fact why a bunch of them haven't gone just to work for Google or by do, is they see ways to save lives right now. If we could reduce the number of deaths on the road by a factor of 100 through intelligent cars, if we could have it so that a poor person who does not have access to elite medical advice can actually talk to an assistant which gives them that kind of advice.
