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.

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.

I don't tell a story unless I have a very deep bench. If you tell an idiosyncratic story, there's no resonance. People read it and say, "I don't see anyone like that." So I tell a story only when I have many stories behind it.

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.

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.

I think few people of education enter politics because it seems like a contact blood sport.

Computers are not good or bad; they are powerful.
