You'd be surprised how often knowing assembly can come in useful - I certainly never expected it. I work in the healthcare sector, which is infamous for having tons of legacy software. At least a couple times a year I end up finding it useful to load some ancient binary into radare2 or Ghidra for debugging, extracting data, or just adding a jmp to avoid a problematic syscall. I'm by no means an assembly expert, but know enough to get the job done.
