A 'blade runner' refers to a character in the science fiction genre, particularly from the 1982 film 'Blade Runner' directed by Ridley Scott. In the film, blade runners are special police operatives tasked with hunting down and 'retiring' (destroying) rogue replicants, which are bioengineered beings indistinguishable from humans. The term has since become synonymous with themes of artificial intelligence, humanity, and dystopian futures.
