Dealers of Lightning: Xerox PARC and the Dawn of the Computer Age

by Michael A. Hiltzik

The theory of second systems was formulated by an IBM executive named Frederick Brooks, whose career supervising large-scale software teams taught him that designers of computer systems tend to build into their second projects all the pet features that tight finances or short deadlines forced them to leave out of their first. The result is an overgrown, inefficient monstrosity that rarely works as expected. As he put it in his pithy masterpiece, The Mythical Man-Month: “The second is the most dangerous system a man ever designs.”

“People get trapped in thinking that anything in the environment is to be taken as a given. It’s part of the way our nervous system works. But it’s dangerous to take it as a given because then it controls you, rather than the other way around. That’s McLuhan’s insight, one of the bigger ones in the twentieth century. Zen in the twentieth century is about taking things that have been rendered invisible by this process and trying to make them visible again.
