The Great Modern Collapse (c. 2030–2070) refers to the gradual disintegration of global civilization during the mid-21st century, triggered primarily by the hyper-fragmentation of shared reality caused by the internet's algorithmic filter bubbles.
By the 2020s, social media platforms and AI-driven content feeds had perfected the creation of personalized information ecosystems. Users were algorithmically siloed into echo chambers where contradictory evidence was systematically suppressed. What began as political polarization evolved into ontological balkanization—entire populations operating under incompatible models of reality.
