No, you won't use it in industry, but...

No, the vast majority of [math, CS algorithms, complex STEM course content] you will never use in industry.

Why is that?

The university can’t justify NOT teaching you the components which went into building the systems we have now. Initially, we needed that deep understanding to be able to build the bridge without it collapsing. Now, since it’s all set up, we don’t touch the fundamentals as much anymore and just build ontop of it all without thinking.

Unless you go for your master’s or PhD, in which case you will need to know that information again.

The point isn’t “I’ll never use this again”, the point is “the school has to teach you the fundamentals, otherwise they couldn’t justify graduating you as a [math, CS, etc.] major”.

A good example: I was taught packet switching in my masters. Everything I touch in a cloud-based computer system relies on this. I can build so much that relies on the technology of packet switching without ever needing to think about it – since it’s already set up for me. The math is already done and the implementation is invisible and ubiquitous. Knowing how packet switching works isn’t useful for my job, but not knowing about it would certainly mean I’m ignorant about a major component of networking knowledge that literally everything we do online rests upon.
