Cyberpunk is a subgenre of science fiction in a future setting that tends to focus on the society of the proverbial "high tech low life"; featuring advanced technological and scientific achievements, such as information technology and cybernetics, juxtaposed with a degree of breakdown or radical change in the social order.
"Classic cyberpunk characters were marginalized, alienated loners who lived on the edge of society in generally dystopic futures where daily life was impacted by rapid technological change, an ubiquitous datasphere of computerized information, and invasive modification of the human body."
— Lawrence Person
