I did not realize this was so rare; my whole team toured a Google data center just a couple of months after I began working there. Perhaps security has grown more stringent in the last eight years. It was interesting, to be sure. I was particularly struck by the amount of engineering that went into the cooling system. I had never really thought about that before. The tour left me with a powerful, pit-of-the-stomach feeling that I had made a big mistake by going to work there. Wasn't the whole point of the PC revolution that we were going to do away with these sorts of massive, centrally-controlled institutions of computing, instead giving the power to the people...? How did we end up back here?
