William Gray Beyer, The deadly thinkers (1951)
“ The men who built, operated and maintained Urei had had but the most nebulous conception of the infinitely complex nature of the completed mechanism. There were blueprints and drawings, of course, but no one human brain could encompass so much territory. Urei's operational crew was comprised of specialists in this and specialists in that, physicists, chemists and technicians; while among them they knew every circuit, every chemical reaction, every relay and every memory cell, there was no ground upon which they could meet and understand just what Urei was and what he could do. ”
