I can't imagine what Pitts would have thought of the rise of chaos theory in physical systems, aka 'sensitive dependence on initial conditions' which was largely discovered with the aid of computers, although Poincare sort of foresaw it He must have been aware of it - control theory involves feedback loops, and numerical robustness is what it's all about. Anti-aircraft rocketry was developed at that point, and Wiener was a central figure, he even called the field "cybernetics".
