And neither is unfixable, it will however impact cost and that's why I think that Tim Cook is not entirely honest here. You can get all this done locally, the skills are there. But those skills are expensive because the same skill level person in the US has a different pay than the person in China. Eventually that advantage will erode and then the locusts will move to the next available third world economy (likely India, or maybe even Africa).
