People can understand that without knowing about bit-shift operators in a given language.
I know about them because I had to. My first computer had 4K of RAM. When I hit the limits of Applesoft BASIC, which didn't take long, I had to learn 6502 assembler. Later, I've done things like writing protocol decoders, so I've also learned them in Python.
But I think it's perfectly reasonable to have a solid career and never use these. To forget that they ever existed, because one is solving problems where they're just not relevant anymore. Our field is too big to know everything, so I think it's fine that people focus on different aspects of the work.
Same here, I started on 6502 assembly and you had to know a lot of that stuff just because we didn’t have cool libraries like the STL and so on. You want to sort something, well you’d better write a sort routine.
