Numerous dystopian worlds have been imagined, i.e. 1984, Brave New World, The Time Machine, V for Vendetta, Brazil, Gattaca, Den brysomme mannen, A Clockwork Orange, Blade Runner, et cetera. They all show us what society might look like and as such it allows us to explore, as we may analyse a chessgame, the consequences of our choices.
Since 1984 is abundantly invoked to warn us against the evil forces du jour this cartoon is a nice illustration of the different threats Orwell and Huxley warned us about. (h/t Library Grape)
