Do Androids Dream of Electric Sheep?
The inspiration for Blade Runner, androids is a curious story that ponders the effects of moving a great deal of the human population off-world - ie into space colonies - and also of using artificial beings to serve humans. discrimination is levelled at hyper-stupid people known as chickenheads; and people use animals as status symbols - a real live animal is a show of wealth. ergo people try to fake it with cheaper artificial animals.
Note that androids is not Blade Runner, it is the inspiration for BR.
