DAMNNN this was short but too good. This is the inspiration for Blade Runner and even though I never watched it, I'm curious in watching it now. The story is set in a distant future where humans have an ''empathy box'' where they can regulate the different brain waves and set the mood they need to be. Empathy is a huge concept in this book. They even use it to discriminate Androids and Humans. They suppose that Androis have less empathy than humans and that's how Rick, android-bounty-hunter use in his test to take out the androids. By asking them a bunch of questions, if they fail to react to the empathy level, it's an android. 
 It's definitely worth a read if you want to explore about AI and what's the future behind the new technologies. (ALSO, If you loved Westworld, I'd recommend this book strongly!!)
