I think it's the other way around, though.
Those code monstrosities aren't comprehendible by humans, especially after the wanton RIFs that have happened in the past couple years that have cut loose a lot of people who know where the bodies are buried.
However, with copilot you can just figuratively walk up to any repo and ask "@workspace what's going on in this codebase" and it'll tell you. From experience I can say this can deliver results. Downright rotten code that would've taken me a good week to figure out can be figured out in an hour. It's damn near witchcraft.
