Everything that enchants may be said to deceive.

These days, when people are alone, or feel a moment of boredom, they tend to reach for a device. In a movie theater, at a stop sign, at the checkout line at a supermarket and, yes, at a memorial service, reaching for a device becomes so natural that we start to forget that there is a reason, a good reason, to sit still with our thoughts: It does honor to what we are thinking about. It does honor to ourselves.

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.

One thing is certain: the riddle of mind, long a topic for philosophers, has taken on new urgency. Under pressure from the computer, the question of mind in relation to machine is becoming a central cultural preoccupation. It is becoming for us what sex was to the Victorians--threat and obsession, taboo and fascination.

What I'm seeing is a generation that says consistently, 'I would rather text than make a telephone call.' Why? It's less risky. I can just get the information out there. I don't have to get all involved; it's more efficient. I would rather text than see somebody face to face.

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.

We have relationships with many different things, creatures and beings. We have relationships with cats, with dogs, with horses, and we know that there are certain things they can't do. So we'll add robots to that list, and we'll learn what they can and cannot do. No harm, no foul.
