Computer science has nothing to do with physical computing devices. Or rather, it has to do as much with computers as astronomy has to do with telescopes. You can do it all on paper. The computing device doesn't afford you anything new, but scale and speed for simulating the mechanical work doing it on paper would. Electrons are irrelevant. They are as relevant to computer science as the species of tree from which the wood in your pencil comes from is relevant to math.

Obviously, being able to use a computer is useful, just as using a telescope is useful or being able to use a pencil is useful, but it's not what CS or software engineering are about. Software is not a phenomenon of the physical device. The device merely simulates the software.

This "centering" of the computing device is a disease that plagues many people.
