Look at the Quayside smart city project in Toronto: Sidewalk Labs promised sensors, efficiency, and harmony, but it collapsed under privacy and affordability concerns. That's the pattern. Systems thinking sounds elegant, optimizing traffic, energy, delivery, but cities aren't just systems. They're messy, unequal, human. A near-future city tuned like a machine will amplify whoever owns the algorithm, not the busker on the corner. I'm against the promise that tech will make cities fairer. Efficiency isn't the same as justice. And without justice, the city's just a prettier cage.
