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.

We expect more from technology and less from each other.

We're in partnership with technology, influencing each other in a dance. My loyalties are to our making and shaping technology to conform to our human values; and to confronting the hard job of figuring out what those values are, and how are we're going to get technology to do that.

If we don't teach kids how to be alone, they will end up only lonely.

People are lonely. The network is seductive. But if we are always on, we may deny ourselves the rewards of solitude.

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.

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