Imagine an alien world where every individual can telepathically communicate with any other individual on their planet (something like Mars in the Miracle of Science sci-fi webcomic). They just think of something, and it happens. They rarely need to move from place to place, and should they visit Earth in one of their alien ships, they would marvel at our traffic jams and office buildings, with our strange habits of going back and forth between two places every single day.

Now think of our world. How far are we from that? We have the Internet, and it's getting mighty close to being a telepathic communications link between us. Someone coming from two centuries ago would have real difficulty understanding how a person sitting at a desk in front of a computer can interact with people and things anywhere in the world (never mind the trouble they would have at understanding the computer itself, that is not important right now).

It's not so hard to imagine the internet as a seamless telepathic link. We're long past the point of using the network without thinking about it. You can take it with you almost anywhere and the medium is rich enough to enable us to do a lot of interesting things. We just need to refine the applications that run on top of it - the building blocks are already in place.
