> In the software world, one will keep bumping into the defect while remains, and there is no guarantee that it will ever be corrected. This is something which does happen in the real world although I don't know that there's a term for it (hence papercut being used instead, as an unnecessary recurring issue which in the grand scheme of things is not exactly deadly — as opposed to sharp edges, which are usually APIs which are tricky to use). For instance it's common to have bits (of varying sharpness) sticking out of walls and other surfaces onto which things or people will repeatedly snag. Or uneven flooring. They are generally minor annoyances people live with, though they can cause actual harm (falls, wounds).
