“Cellphones have changed how we communicate with others, and now they are changing how we think about information,” argues John Markoff of the New York Times.
“With the dominance of the cellphone, a new metaphor is emerging for how we organize, find and use information. New in one sense, that is. It is also as ancient as humanity itself. That metaphor is the map. [...]
As this metaphor takes over, it will change the way we behave, the way we think and the way we find our way around new neighborhoods. As researchers and businesses learn how to use all the information about a user’s location that phones can provide, new privacy issues will emerge. You may use your phone to find friends and restaurants, but somebody else may be using your phone to find you and find out about you.”
