In the future, probably most of the content and most of the traffic on the Internet will be computers talking to each other. At Google, we actually download the entire web. We do this every month, and in the future we ll do it much more often. That generates a lot of traffic. It s not a simple thing to do.
People back up their computers.
Your computer might have all the movies that you d be interested in watching just stored on a computer and ready to go. So those all have to be transferred over the network. That will lead to very fast scientific advances in a lot of areas. The other main issue I see with networks is that you have very limited access to the Internet. There are only a few people in the world who have DSL or cable-modem speed access for the Internet.
