Blade Runner, originally a novel titled 'Do Androids Dream of Electric Sheep?' by Philip K. Dick, is a seminal work of transhumanist dystopian science fiction. The story is set in a future where androids, known as replicants, are indistinguishable from humans. The protagonist, Rick Deckard, is a bounty hunter tasked with 'retiring' rogue replicants. As Deckard delves deeper into his mission, he questions the nature of humanity and the ethics of creating artificial life. Blade Runner explores themes of identity, empathy, and the blurred lines between man and machine.
