The mythical expert programmer...

Everyone has a cognitive limit on what they can keep track of/in working memory. Once your codebase exceeds that limit (in # of files, lines of codes, types, interfaces, etc.) you lose productivity. 10k lines of python is a lot harder to grasp than 10k lines of go.

And that's not even considering the ramp up time for someone new to the code to jump in, which is even worse in most dynamic language codebases.
