Think of the marvels of buying and selling world-wide. This is really what globalization means. We are seeing only the first glimpses today. As always, new forms will drive new content and use. It just takes a lot longer than we would like.
Email is a prime example.
We still call it mail, just as the iron horse and horseless carriage were terms used long after they made sense. But it is really nothing like mail. As long as we dignify it as mail, it will drive us crazy. We need to recognize it as something radically new. No filter, no privacy, no filing, no follow up.
