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.

Terrified of being alone, yet afraid of intimacy, we experience widespread feelings of emptiness, of disconnection, of the unreality of self. And here the computer, a companion without emotional demands, offers a compromise. You can be a loner, but never alone. You can interact, but need never feel vulnerable to another person.

In the area of robotics and in the area of connectivity, technology is offering us things that we are vulnerable to - and we have to have a better response than a shrug.

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.

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.

My own study of the networked life has left me thinking about intimacy - about being with people in person, hearing their voices and seeing their faces, trying to know their hearts. And it has left me thinking about solitude - the kind that refreshes and restores. Loneliness is failed solitude.

We ask [ of the computer ] not just about where we stand in nature, but about where we stand in the world of artefact. We search for a link between who we are and what we have made, between who we are and what we might create, between who we are and what, through our intimacy with our own creations, we might become.
