Le congrès de futurologie

The Futurological Congress (Polish: Kongres futurologiczny) is a 1971 black humour science fiction novel by Polish author Stanisław Lem. It details the exploits of the hero of a number of his stories, Ijon Tichy, as he visits the Eighth World Futurological Congress at a Hilton Hotel in Costa Rica. The book is Lem's take on the science fictional trope of an apparently Utopian future that turns out to be an illusion.
