So I'm almost certainly in a different industry (embedded) where EEs tend to prolifically copy+paste code. In the end this always makes it so that a change that should take very little time consumes an entire workweek or more. So I have a seething hatred of this practice from past experiences.

I suppose I should say that there's a lot of different types of duplicate code, some of which really don't matter per se. Sometimes two bits of code are basically the same but are completely unrelated and as things change they will diverge, i.e. it was just incidental. Code that is duplicated with a strong functional relationship make changes a nightmare though.
