And you also don't solely blame the iPhone. No, that's right. There's two parts. There's more to it. That's why I think it's so intriguing. Well, thank you. Yes, people tend to focus on the phones because that's what we're all, I mean, we're all in the midst of it. But there's a longer backstory. And thanks for giving me the invitation to tell that.
