In contrast, I've worked on 2 UI frameworks and knowing all about tree traversal was super useful. I've sat next to the engineer who had to write various sort algorithms for the embedded runtime I helped design. I've witnessed a file system get implemented from scratch. I have walked through the Windows' kernel source code and knowing my fundamentals sure as heck helped to keep me grounded. > (and if there aren't, that's often a big red flag that you're doing something wrong). Or that you've chosen a career building the layers that underpin everything else. I've found that life is more enjoyable when I understand how things work at a base level, and remembering my fundamentals opened up doors to work on cool projects.
