> Consolidating code is easy, pulling it apart is a lot harder. I absolutely agree with this, and the only thing I would add is that is difference is even more pronounced in codebases using a dynamic language. Sure it's not easy to navigate a bowl of duplicated spaghetti, but navigating opaque DRY service classes without explicit types is a nightmare. Luckily as an industry we've realized the benefits of static typing, but your point still holds true there.
