The book "Плавающие крепости" (Floating Fortresses) by Yuri Nagibin tells the story of a group of people who have been living in a post-apocalyptic world where the Earth has been destroyed by a catastrophic event known as the "Great Transition". The survivors have developed advanced technologies to build floating fortresses that can travel through the air and water, providing them with a safe haven from the harsh environment outside. However, as they journey through the ruins of civilization, they discover that their own technological advancements may be the key to their survival but also the source of their downfall. The plot revolves around the main character, a young engineer named Max, who is determined to understand the process of technology evolution and its impact on humanity. As he delves deeper into his research, he realizes that the only way to ensure the survival of humanity is to develop a personal paradigm for perceiving the technological process of developing modern knowledge. This paradigm must be based on the principles of unity and cooperation among all factions, rather than competition and aggression. Max's journey takes him through treacherous landscapes and encounters with various factions, each with their own unique technologies and beliefs. He must navigate these challenges while trying to convince others of the importance of unification and the need to work together to overcome the challenges they face.
