"NP-hard, tedious, or just unsolved — what problems need a brute-force / OS-style tool built for them?
While learning C++ / OS / Computer Architecture, I keep looking for real unsolved(ish) problems to anchor the theory in — rather than just doing textbook exercises. Curious what "sounds impossible but is actually solvable with enough engineering" problems you've run into in industry. What's on your list, and did you end up building tooling for it?
