This Perfect Day Ira Levin
This Perfect Day is a science fiction novel by American writer Ira Levin, about a technocratic dystopia.
"The world is managed by a central computer called UniComp (referred as just "Uni" in speech), which has been programmed to keep every single human on the surface of the Earth in check."
"Chip succeeds in destroying Uni with the explosives. On his way up from the underground city towards sunlight, Chip tells an angry programmer: "'There’s joy in having it': those were [Wei's] last words. Everything else was rationalization. And self-deception."
