DIY City: An Operating System for Cities

John Geraci (DIYcity)
Location: Regency Ballroom

Our cities today are outdated models of inefficiency, consisting of centralized, top-down and non-participatory services and infrastructures. The results are spiraling city deficits, ballooning bureaucracy, and an inability to pay for basic services, paired with problems of wasted resources, scarcity and redundancies. The way to solve these problems is for cities to become more like the web, relying on decentralized, distributed, participatory and geo-aware services built with open source software than anyone can configure, maintain and improve. The resulting system will transform our cities into leaner, more efficient places as well as more engaging, more participatory and friendlier communities in which to live.
