In 2021, Saudi Arabia promised a 170km mirror city. By late 2025, it was a ruin. Today, we perform an autopsy on the most ambitious construction project in human history—and reveal the terrifying "Smart City" replacing it. The Line was supposed to be the next stage of human evolution—a vertical utopia for nine million people. But physics, economics, and the harsh reality of the Tabuk desert had other plans. In this Neo Civitas briefing, we uncover the engineering failures behind the "Missing 168km," explore the "Wind Tunnel Effect" that doomed the project, and investigate why the gigaproject era ended in a budget meeting. But while the world watched NEOM crumble, Toyota silently switched on a different kind of experiment in Japan. The era of the Megastructure is over. The era of the "City of Sensors" has begun. 0:00 The Corpse in the Desert (Current State of NEOM) 3:30 The Math of Failure: Why Physics Hated The Line 5:00 The "Hidden Marina" Excavation Disaster 8:00 History's Warning: The Curse of Linear Cities 11:00 The Pivot: Woven City & The Death of Privacy 12:15 Conclusion: The New Urbanism Sources: Saudi Sovereign Wealth Fund (PIF) 2025 Report Toyota Woven City Phase 1 Press Kit "Roadtown" by Edgar Chambless (1910) Nature Journal: "Atmospheric Vortexes in Vertical Cities" #theline #neom #urbanplanning #engineering #megaprojects #saudiarabia #Wovencity #futurecities #documentary #NeoCivitas #future #futuretech
