In a thought-provoking 'design fiction' exercise, design researchers Bleecker and Nova invert the discourse of instantaneity in urban computing and digital cartography (Bleecker and Nova, 2009). Urban new media tend to promote a speeding up of time: there is here a conspicuous arms race towards more instantaneity, more temporal proximity between events, people and places. Communication is promoted to be 'just-in-time'; feedback to your activities should be in 'real-time' as if you were playing a video-game character. Speed is essential, and this never-ending battle with time-to eliminate it-makes things happen instantaneously. (Bleecker and Nova, 2009: 29) By elevating 'real-time' to a prime design objective, urban new media in fact are geared to dispose of time-in the sense of duration-as a limiting factor altogether. Bleecker and Nova forward the notion of asynchronicity to explore how urban computing technologies might afford more diversified interactions than the efficiency-driven real-time model: there are many geographies, asynchronous because we have individual experiences of the world. Fixed things become flows, and flows become the fixed point of reference … Perhaps we learn from this that computing in an urban setting should first of all not be about data and algorithms, but people and their activities. What happens when time everywhere is not synchronised, when it floats and lags a bit? (Bleecker and Nova, 2009: 19)
