Go has no expressiveness to it. You end up either with a large pile of copy pasted code, code generators, or massively error prone runtime introspection. Go blows up the entire idea of Don't Repeat Yourself. The language actively encourages it.

Yes, this is true. I programm in Go professionally, about 50% of my work time (other half is python). But in many cases, I have found that copying the same code to other places doesn't have that much negative consequences as one would believe.

Refactoring becomes intensely burdensome, often to the point that it is avoided at all costs. Not a great situation when you need to iterate on a design.

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.
