Thus, it matters a great deal, in terms of what actually gets designed, whether or not the designers and users are the same people, whether or not they know each other, whether or not they view each other as equals, whether or not they have power over each other, whether or not they are friends. On the whole, technical people come to share the perspective of those who wield power rather than those over whom the power is wielded, with managers rather than labor, with officers rather than soldiers. If for no other reason, this happens simply because technical people do their work almost exclusively with the former rather than with the latter, and come to share a world with them. But they have very little, if any, contact with the others, about whom they typically remain woefully ignorant.
