I am very much struck at category meetings what a variety of backgrounds the participants come from, lots from computer science of course, and now increasingly many physicists. It seems to me this is exactly because category theory has the qualities you describe. It enables the pure category theorists, the computer scientists, the physicists to meet and talk together with a high degree of mutual understanding. I don't think of myself as a pure category theorist, but I can't imagine trying to do what I do without it. All the best, Steve.
