Science fiction

In literature, science fiction (often shortened to sci-fi) is a genre of fiction in which the story's events take place far in the future.
Science fiction contains a number of sub-genres:
* Dystopia - the future world is a bad place to live in, with society being too power-abusive and usually enforcing ridiculously strict laws.
* Post-apocalypse - after an apocalypse occurs, the remaining people alive struggle to revive society.
* General - in the far future, people use very advanced technology to live out their lives. Usually, a malfunction occurs that turns machine against man that must be fixed.
* Cyberpunk - a future with advanced technology and a change to the social order, often echoing elements of film noir and with a sense of rebellion. These stories tend to be set in a future Earth that is in a post-industrial dystopian society, and they are usually marked by extraordinary cultural ferment and the use of technology in ways never anticipated by its creators.
