Humans and computers are two alien races that often fail to communicate smoothly (or at all), despite one race having created the other. In their wisdom, computing professionals have not
failed to note this alienation problem. Entire fields—such as software engineering and computer-human interaction— have sprung up over the years to ameliorate this unfortunate alienation.
To make clear that this is a serious business, our fellow professionals coined the term “user,”
just as doctors refer to those to whom they minister as “patients.” However, if they ignore the feelings of their supplicants, both doctors and computer designers may be failing to take seriously enough their respective workplace oaths.
