Paul Virillio The overexposed City

Virillo's article also made me think about city as a geographical space. A historical city as we know it is so obviously different from what we have today. But the thing I was drawn to think about is the city as a measureable place. How big is the city you live in? The city seems to be a certain size based on how much space it physically takes up. However when I think about my definition of a city. I begin to think about what connects the city, what helps the city to grow and function. Isn't the internet apart of the city? Do computers not run most everything that we do? Everyday some many phone calls are made that we can barely keep up with all of them. These phone calls exist in a wave of there own. We cannot occupy any of this space, but it is a space that makes up our city. Should we not then include the space these take up into our calculation of city? I guess the idea of city is a subjective term. A city could fit into a small block but the virtual space that occurs along side the physical could be quite large. How we begin to rethink our definitions of city, size, boundaries and geography?
