The thing is, as compute prices fall and AI advances in its capability, swarms of coding agents can sweat on every line of code, looking for cleaner implementations, testing them, 24hrs a day. Current models often produce spaghetti crap. But it's a bold assumption that will always be the case.
There's a pretty big herd of sacred cows in programming and this debate always surfaces them. But I remember similar arguments being made about Go once and its version of human beings' special something. We saw then that sacred cows don't live long when AI really arrives.
