This book is weird.  I don't quite understand what the exact story the author was trying to tell, but it went through some weird events.  I get the idea, robot/ai stops humans from reproducing.  But it was difficult to read, maybe I don't enjoy dystopia about losing control of one's self, akin to the use of drugs, etc.  Maybe it was also the lack of enjoyment from any of the characters, they all seemed to really have little motivation.
