Using an absolute like "never" is surely a good way to generate conversation. That said, it's probably more likely you won't go back and fix it, but I have plenty of recent examples where I have committed myself to going back and refactoring things which have been and would likely continue to work for some time, if not "indefinitely" (read: for the life of usage). Depending on what it is, sometimes the mental burden of working in a system full of corner-cutting decisions is worse than the burden of rewriting it.

Or, perhaps, I get a large hit of dopamine from refactoring poorly-thought-out systems.
