Apple's Going to Face a Change in Supply Chain, Right?

It can't be easy to make a move of this magnitude. I'm just wondering what kinds of challenges, what kinds of roadblocks might Apple expect to encounter as it makes this shift in sourcing? No, it's absolutely not easy. As anyone who's done it or tried to do it will attest to. You can group sort of challenges into two really, I think firstly on the set up challenges. And we've seen examples of this with TSMC investing into something like $40 billion.
