Every piece of code will stop working at some point if you keep working on the software (and the software itself will probably stop being compatible with other softwares if you stop working on it).
And, if it stops working, do we have some reason to conclude that we won’t know why?
If you don’t know why it works in the first place, it’s a pretty good assumption that you won’t know why it doesn’t work, either.

I thought that you were talking about Torvalds’ attitude, given the context.
