Today Google Maps adds Chicago to its "Street View" function, so that urbanites' activities in all their banality are memorialized until the next image refresh. No one cares that their phone may be tapped, but they get incensed if someone tries to photograph them unloading groceries.
The Street View is neither a panoptic intrusion into our private lives nor Walter Benjamin's utopian concept of a public space in which people feel as comfortable and as empowered as they do in private space. Rather, the Street View is a symptom of a reality deficit, in which everything is so indexed and classified that there's nothing left to discover. It's an anti-dérive.
