Seriously, computer science itself is a branch of mathematics. Or is mathematics a branch of computer science...?

It's not always weird bit-level arithmetic, but if you aren't using math at some level, you're not programming; you're just futzing around with a text editor.

Well, at some level almost everything can be described as using math. However, loads of software used by millions and netting millions can be and is written by people who most would describe as barely mathematically literate, from most sorts of business/accounting software (unless arithmetic is math) to device drivers to dating sites (where you could and will use heavyweight machine learning to match people but it kinda seems that having actual people on the site delivers 99.99% of the value regardless of said machine learning.)

There are counter-examples in every area, of course, it's just that the majority of programmers out there aren't great at math and are very much employable. And more often than not, people who're really great at math go to great lengths to avoid programming even when their work revolves around computers.

CS is a branch of math, of course, but this fact happily co-exists with all of the above.
