The structure of this book vaguely reminded me of David Mitchell. Each individual story is interconnected by different links, whether it's the subject matter, an actual character or place or an idea. While the book, on the surface, is about our reliance on computers and increasingly realistic AI, the stories tended to speak more to the characters human interaction and their remorse at having neglected those relationships in favor of computers. At least that's what I took away from it. That and the lesson that no matter how realistic our interactions with computers, they cannot take the place of human interaction. 
 The characters talked in the first person through memoirs and letters. One character's story was related through a transcript of the conversations she had with MARY3, a chatbot and one of the major links throughout the stories. 
 While the idea and structure of the book was interesting, the characters that inhabited it were not. I didn't feel moved at all by their various plights. But the ethics and questions raised by the book are definite food for thought.
