People in the current year (2012) have had little to no exposure to telephones that used rotary dials, but we still use the terminology to dial a phone. Or, if there are no telephones in the year 2025, the term hang up will have only archaic meaning.
Another song example is Jim Croce's song Operator, recalling the time when telephone operators (usually female) assisted with making connections (see video above).
Just like media and technology give us new words and new meaning for words, they also give us new and different metaphors for how we relate to other people, and to other things around us.
