And that's why the millennials' mental health didn't plunge. Talking on the phone is great. Texting is not as good because it's not synchronous, but it's not bad just with your friends. But what happens by 2015? Actually, let's look at 2013 when this all starts. Everyone's trading in their flip phone for a smartphone. They're getting off of Facebook on their parents' computer.
