Dijkstra: "Computer Science is no more about computers than astronomy is about telescopes." (Since nobody's said it explicitly and in case you were referencing it.) That is, telescopes are, in practice, the most common way to learn about stars(/celstial bodies), but the stars are the target of study, with telescopes an incidental tool. Computer science is about e.g. resource scaling for solving particular problems, with electronic computers just being one way those insights can be applied.
