Young people realize that something is amiss. There's a generation that fell in love with their phones, and it's very hard for them to see that there's a problem. But young people are desperate for the attention of their parents, who are really not paying attention to them.

People put on their earphones, they lay out their phones, they put - open up their computers, and they convince themselves that they're most productive when they're focused on their e-mail, when, really, they're ignoring the cafeteria, the watercooler, the meetings with colleagues, the times when really the creativity, collaboration happens.

All the research shows that the presence of that phone will do two things to the conversation. It will make the conversation go to trivial matters, and it will decrease the amount of empathy that the two people in the conversation feel toward each other. That phone is a signal that either of us can put our attention elsewhere.
