Artificial intelligence is everywhere, and it’s getting smarter. It’s driving cars, screening resumes, monitoring surveillance networks and even helping doctors make medical diagnoses.

Tulane computer scientist Nicholas Mattei is a co-author of Computing and Technology Ethics: Engaging through Science Fiction, a book coming out this fall about the growing field of AI ethics. Mattei talks about the risks when developers don’t ask the right questions and whether AI has the potential to take over if we’re not careful.
