It’s a way of life to be always texting and when you looks at these texts it really is thoughts in formation. I do studies where I just sit for hours and hours at red lights watching people unable to tolerate being alone. Its as though being along has become a problem that needs to be solved and then technology presents itself as a solution to this problem…Being alone is not a problem that needs to be solved. The capacity for solitude is a very important human skill.

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.

Teenagers talk about the idea of having each other's 'full attention.' They grew up in a culture of distraction. They remember their parents were on cell phones when they were pushed on swings as toddlers. Now, their parents text at the dinner table and don't look up from their BlackBerry when they come for end-of-school day pickup.

When the social network doesn't find it convenient to have privacy, we say, "Okay, social network, you don't want privacy, maybe we won't have it either." But we did this without having the conversation.

Human relationships are rich and they're messy and they're demanding. And we clean them up with technology. Texting, email, posting, all of these things let us present the self as we want to be. We get to edit, and that means we get to delete, and that means we get to retouch, the face, the voice, the flesh, the body -- not too little, not too much, just right.

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.

What is so seductive about texting, about keeping that phone on, about that little red light on the BlackBerry, is you want to know who wants you.
