Digital modeling is a pretty block-headed way to go about building a simulation. And when computers were slow and tubes and memory were very expensive it seemed even more block-headed. The main advantage was flexibility so as digital computers got faster and cheaper they ate more and more domains where analog computers might have seemed more ideally suited.
