How do we make AI safe, how do we create robots that are positive and empowering companions for humanity? Asimov proposes his three famous laws of robotics, but uses this book to explore the potential shortcomings of any such moral framework. I was surprised to find his stories be applicable to many current discussions regarding ethics and morale of the AI to come. This was the first by Asimov that I've read. It won't be the last.
