My day job is relatively boring JavaScript components and SPA's, but even there I find things I learned in my Computer Science degree valuable. "Hey, this looks like a finite state machine.." "This could be a simple domain specific language, good thing I had to write compilers in college and I can easily make a simple lexer/parser.." "This other thing is easy to parse if I ingest it into a lexer-resembling state machine.." And I would think the value of understanding algorithmic complexity and so many other fundamental things is obvious, no matter what someone is doing. And you won't waste your time accidentally trying to solve the Halting problem, among other things. Obviously there's nothing a university can teach you that you couldn't theoretically learn somewhere else but I'm seriously not convinced that a Computer Science degree is useless or a poor signal even for someone doing run of the mill React apps.

I'm jealous. My university did not make that a core class of our degree. While in hindsight, I wish they did. I did have the luxury of a lot of low-level exposure, which has served to be quite useful at times (digital logic, assembly, etc.).
