Just as punch cards gave way to command lines gave way to graphical user interfaces gave way to multitouch user interfaces, and may one day give way to natural language user interfaces, people who could build their own computers gave way to people who could write to the metal of their computers gave way to people who could point and click their way around their computers gave way to people who could touch their computers and may now give way to people who can simply talk to their computers, the definition of a power user has, is, and will keep on growing.
