Postman: the dominant metaphor of our age

[Bolter argues that the computer is] the dominant metaphor of our age;  it defines our age by suggesting a new relationship to information, to work, to power, and to nature itself.  That relationship can best be described by saying that the computer redefines humans as 'information processors' and nature as information to be processed.  The fundamental metaphorical message fo the computer, in short, is that we are machines - thinking machines, to be sure, but machines nonetheless...it subordinates the claims of our nature, our biology, our emotions, our spirituality.  The computer claims sovereignty over the whole range of human experience, and supports its claim by showing  that it 'thinks' better than we can.
