Andrew Blum, Author “Tubes: A Journey to the Center of the Internet”

After you hit send on an email or search on Google or click a hyperlink on a site via Internet Explorer, what happens? I don’t mean what happens like — the email sends or the search searches or the hyperlink links. I mean how does the email send? How does Google search a gazillion places for millions of results in nanoseconds. I mean how does the Internet work? What’s it made of? Is Cyberspace a place? I have no doubt that if Lewis and Clark were alive today, this is the land they would try to discover. This is the unmarked territory, our manifest destiny, but who can map it? Andrew Blum can. A journalist who writes about architecture, technology and infrastructure, Blum is now the author of “Tubes: A Journey to the Center of the Internet” and he joins us now. (Originally broadcast 9-8-12 on The John Batchelor Show)
