Powerful short essay [2] on the digital revolution. The map has become the territory. “We assume that a search engine company builds a model of human knowledge and allows us to query that model, or that some other company builds a model of road traffic and allows us to access that model. This fits our preconception that an army of programmers is still in control somewhere, but it is no longer the way the world works. The search engine is no longer a model of human knowledge, it is human knowledge. If enough drivers subscribe to a real-time map, traffic is controlled with no central model except the traffic itself. The social network is no longer a model of the social graph, it is the social graph” (1,250 words)
