This small book seems to be a quick read but it is anything but. Despite being written several decades ago, its content is heavy and relates to many of the ongoing discussions in the modern world. How do we handle artificial intelligence as they gain more intelligence, gaining something that feels like empathy and morals. Should corporations in charge of and creating artificial intelligence have a responsibility in making them more and more technologically advance? How do we handle ownership of A.I.? Another part of the book deals with the ableism of another character. He was unable to evacuate the earth when it started dying due to his lower I.Q. The book might date itself (i.e. referring to Russia as the Soviet Union), but this book has much relevancy to day.
