This is the wrong question. CS isn't hardly about code. Most of our CS today is from before the 1950s.

You're correct that CS isn't about code. Programming is, and that's what I was drawing the comparison with.

Most of the CS we have from pre-1950 is fundamentally mathematics: algorithms, theory of computation, etc.
