Jonathan Nolan and Lisa Joy, the creators of WestWorld, discuss discuss the sci-fi themes and other issues around WestWorld.

I found this excerpt particularly interesting:

Question: How do you achieve a balance between the mindless and the more high-minded concepts?

Nolan: That question is very much at the center of what we’re doing. The trend is toward human beings’ ability to turn more and more of their world into game space and narrative space[...]Why are many of these narratives so violent? And the series very much asks the question: What the fuck is wrong with us?
