The book is titled: "Do androids dream of electric sheep?"
The title "Bladerunner" came from an Alan B. Nourse Novel in which medical care was rationed and the general public could only get it by hijacking ambulances and stealing medical supplies as they were being transported between heavily fortified elite enclaves of the wealthy.
I never could see the relationship between "Bladerunner" and the "Android" movie that was made. The only one possible was the gritty setting with the rich living in enclaves and the proletariate living in basic squalor and there being little connection between the two.
No, I mean the actual book titled “Bladerunner”. Yes, the story that was eventually turned into the Movie was called “Do androids dream of electric sheep”, but that’s not where the title came from.
