Wifi = Computer Telepathy

If you think about it, probably the reason wireless networking and mobile phones are so successful and exciting and desirable to humans is that they remove the barriers of space, matter and to some degree, time from communication.

Wireless networking is the fastest, most frictionless form of communication between devices yet. This closely approximates telepathy, which would be the fastest most frictionless form of communication possible between people (aside from simply knowing, but that wouldn't be communication strictly, it would be an alternative to communication).

My father pointed out that you could also look at mobile phones in this light: they are similar to telepathy, because they remove time and space from communication, and thus they more closely approximate a level of communication dependent on energy more than matter or space.

While time still factors in the communication in that the people need to be talking in the same general time regardless of their location, there is a certain amount of time independence as well because you do not need to take time to get near the other party in the communication - you can ring up or connect someone around the world and communicate with them as if they were in the same space without added time.
