The act of computation can be done with abacuses, gears and mechanical linkages (Babbage difference engine and other mechanical computers), fluid logic, and a variety of other mechanisms. The means of implementation has little to do with the mathematics of computing itself. Astronomy isn't about telescopes, as Dijkstra famously noted in his analogy about CS, but it's difficult to deny that astronomers wouldn't have much to do other than twiddle their thumbs without the aid of them. Computer engineering is about building the telescopes.
