Cyberpunk is a subgenre of science fiction that is set in a dystopian future and focuses on a combination of lowlife and high tech. It features futuristic technological and scientific achievements, such as artificial intelligence, virtual reality, and hacking. Cyberpunk settings are often dystopias with corruption, computers, and computer networks, where giant multinational corporations have replaced governments as centers of political, economic, and even military power. The genre is renowned for its grim and gloomy depictions of a world where technology has gone beyond human control and produced new kinds of exploitation and oppression. Cyberpunk culture is anti-authoritarian, brand-averse, and tech-literate, and it often expresses a sense of rebellion, suggesting that one could describe it as a type of cultural revolution in science fiction. Cyberpunk is also characterized by its neon-lit cityscapes, gloomy, crumbling cityscapes, and a general atmosphere of decay and dystopia. Cyberpunk can be intended to disquiet readers and call them to action. The genre has evolved over time and will probably continue to do so in the future.
