Speculative futures: Cities, data, and governance beyond smart urbanism
本文探讨大数据与城市治理的融合，指出除了智慧城市中的自动化管理，还应关注算法治理如何通过预测未来（如规避风险）来塑造城市，并以手机安全应用和情感分析为例说明其不平等性。
In this paper, I examine the convergence of big data and urban governance beyond the discursive and material contexts of the smart city. I argue that in addition to understanding the intensifying relationship between data, cities, and governance in terms of regimes of automated management and coordination in ‘actually existing’ smart cities, we should further engage with urban algorithmic governance and governmentality as material-discursive projects of future-ing, i.e., of anticipating particular kinds of cities-to-come. As urban big data looks to the future, it does so through the lens of an anticipatory security calculus fixated on identifying and diverting risks of urban anarchy and personal harm against which life in cities must be securitized. I suggest that such modes of algorithmic speculation are discernible at two scales of urban big data praxis: the scale of the body, and that of the city itself. At the level of the urbanite body, I use the selective example of mobile neighborhood safety apps to demonstrate how algorithmic governmentality enacts digital mediations of individual mobilities by routing individuals around ‘unsafe’ parts of the city in the interests of technologically ameliorating the risks of urban encounter. At the scale of the city, amongst other empirical examples, sentiment analytics approaches prefigure ephemeral spatialities of civic strife by aggregating and mapping individual emotions distilled from unstructured real-time content flows (such as Tweets). In both of these instances, the urban futures anticipated by the urban ‘big data security assemblage’ are highly uneven, as data and algorithms cannot divest themselves of urban inequalities and the persistence of their geographies.
