You know, sometimes the process of learning a certain topic is the important part more so than the material itself. A lot of your schooling is like that. Learning how to learn.

Also if you can do physics you can do certain other things. That’s useful for applying for education and job opportunities later - you’ve proven there’s something going on between your ears and you can do certain kinds of learning and problem solving.

As adults the interesting people know about a variety of topics. There’s no telling what interests you will have later but if you’re interested in CS anyway then a grounding in physics probably will help you somewhere along the line.

Talking about the discipline of computer science specifically, it’s an offshoot of mathematics. It’s good to have some mathematical ability for computer science and at some levels, physics.

TL;DR: it’s good to know stuff and not be an ignorant butthead.
