Grow away from a very close real future, we can touch a speech more about sci-fi field.
The network is like a huge brain, where the pulse (data) produce actions in a kind of continuous exchange of information. Well, in this context, it's natural for humans to daydream future development of technology applied to themself.
Books, movies (especially the cyberpunk genre) and various documents, have generated scenarios and future prospects unthinkable, but at the same time plausible. Even now you can use modern technology and combine with the human body: for example, the remote control of the appliance
support to the human body, prosthesis, valves... In this point of view, we can translate the nerve impulses in data and create a link with the network.

Think a human with his brain connected to the network: no more device, computer... man himself is all of this. Of course, this science fiction vision has unimaginable moral implications, but it's fascinating and interesting to think about this wired world.
