A key theme in Blade Runner is that it depicts postmodernism throughout the film by blurring the differences between the real and the artificial. In the movie, there is a scene where Rick questions Leon to see if he can elicit emotions to determine whether he is a replicant or a human, which shows that no one really has a clear understanding of what which is real. Blade Runner also addresses the theme of space-time compression, not only through the presence of flying cars that decrease the time it takes to get anywhere, making information and travel much faster, but also by ensuring that the lifespan of the replicators is only four years. time is less relevant because of the amount of living they must accomplish in one fifth of a human being's life. The theme of creative destruction is also presented in a scene where they explain what the Blade Runner is and how his job is to catch and "remove" the replicants because they have started to rebel and they must make sure they don't become one.
