Tom Vanderbilt:

Who and where was this invisible metropolis? What infrastructure was needed to create this city of ether?

Much of the daily material of our lives is now dematerialized and outsourced to a far-flung, unseen network.

The tilting CD tower gives way to the MP3-laden hard drive which itself yields to a service like Pandora, music that is always “there,” waiting to be heard.

But where is “there,” and what does it look like?

Have you read Vanderbilt's "Traffic"?

Ultimately, Traffic is about more than driving: it’s about human nature.
