The computer is a mind machine. It doesn't have its own psychology, but in a way it presents itself as though it does.

We will continue to live in a form in which we become cyborg. Either we download our information to a machine or we incorporate so many machine parts that we don't know where we end and the machine begins.

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.

Kids have moved from, "I have a feeling, I want to make a call," to "I'd like to have a feeling, I need to send a text." In other words, there's a continual need for validation. They're constituting a thought or feeling by sending it out for votes. That's really not where you want to be emotionally.

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.

The kind of solitude that refreshes and restores is very important, not just for children, not just for adolescents, but for all of us. If you don't teach your children how to be alone they will only be able to be lonely.

I love sharing photographs and websites, I'm for all of these things. I'm for Facebook. But to say that this is sociability? We begin to define things in terms of what technology enables and technology allows.
