Yes, interchangeable parts are a central component of mass production. And you have to remove the application of skilled labor to get to interchangeable parts, because that requires mechanization, not the intensively individualized input of skilled workers.

But of course the reality is far different. Monkey no troubleshoot or bug-hunt. You need humans for that. Skilled labor.
