A while back, a highly-educated friend and I were driving through an area that had a lot of data centers. She asked me what all of those gigantic blocks of buildings contained. I told her that they were mostly filled with many servers that were used to host all sorts of internet services. It completely blew her mind. She had no idea that the services that she and billions of others used on their phones actually required millions and millions of computers to transmit and process the data. I'm not sure how she thought it worked, but even after I explained it to her, she couldn't comprehend that there were servers on the other end of her phone. Magic.
