It's a thing of its own. Used to be called informatics in some countries. Much better name, IMO. There are large parts of computer science that have nothing to do with computers. They're about information and can be applied outside of computers.
I'm with Alan Kay when he says "computer science" used to be an aspiration and eventually became a misnomer. Same with software engineering.

(Doesn't mean CS and SE are always "worse" than science and engineering. But they are currently very different.)
