Benjamin Bratton characterizes the third and final presentation for the Architecture, Computation and Globalization seminar as an exploration of how the emergent planetary-scale computational infrastructure discussed in his previous talks relates to cities. He discusses the airport as the urban space of hard and soft control, and new digital gateways which control access without capturing bodies. Bratton discusses the physical organization of the crowd performed by the building envelope and virtual envelopes. He discusses generative design in the context of the new cities being built around the world like Masdar City and Songdo. Bratton responds to comments from the audience about surveillance, airports as sites in which the city is repeatedly miniaturized, and dis-enchantment as a call to arms.
