We are entering a world where there won't be one but two realities, just like we have two eyes or hear bass and treble tones, just like we now have stereoscopy and stereophony: there will be two realities: the actual, and the virtual. Thus there is no simulation, but substitution. Reality has become symmetrical. The splitting of reality in two parts is a considerable event which goes far beyond simulation.
Paul VirilioMoreover, I would like to say that the sort of polar inertia we witnessed in the Kosovo War, the polar inertia involving 'automated war' and 'war-at-a-distance' is also terribly weak in the face of terrorism. For instance, in such situations, any individual who decides to place or throw a bomb can simply walk away. He or she has the freedom to move. This also applies to militant political groups and their actions.
