Telephone companies sell us voice plans because they know we're not going to use them. We're hiding from each other. People say that calls aren't efficient, but trying to bring efficiency into your intimacy can get you into a lot of trouble.

As a therapist, I know that when you're vulnerable, the best way to move on is to admit your vulnerability, don't beat yourself up for it, and try to find a way to analyze your vulnerability. Pull up your socks and try to do better for you and your family.

If you're happy with where the Internet, Facebook, and Twitter have taken you, I'm not the Grinch. Someone called me Sherry Turkle's "evil Luddite twin." I'm not that. I enjoy the bounties of this technology. But if you fear that your connected life is running away with you, read the book, reflect, talk to your family and friends. I think we deserve better than some of the places that we've gotten with this technology.

Pinball games were constrained by physical limitations, ultimately by the physical laws that govern the motion of a small metal ball. The video world knows no such bounds. Objects fly, spin, accelerate, change shape and color, disappear and reappear. Their behavior, like the behavior of anything created by a computer program, is limited only by the programmer's imagination. The objects in a video game are representations of objects. And a representation of a ball, unlike a real one, never need obey the laws of gravity unless its programmer wants it to.

Networked, we are together, but so lessened are our expectations of each other that we can feel utterly alone. And there is the risk that we come to see others as objects to be accessed—and only for the parts we find useful, comforting, or amusing.

We're lonely, but we're afraid of intimacy. And so from social networks to sociable robots, we're designing technologies that will give us the illusion of companionship without the demands of friendship.

We're in partnership with technology, influencing each other in a dance. My loyalties are to our making and shaping technology to conform to our human values; and to confronting the hard job of figuring out what those values are, and how are we're going to get technology to do that.
