People thought I was very pro-computer. I was on the cover of Wired magazine. [Then things began to change. In the early 80s,] we met this technology and became smitten like young lovers. But today our attachment is unhealthy.

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.

Robots want to love us because the field of artificial intelligence has programmed robots to say they want to love us.

Does virtual intimacy degrade our experience of the other kind and, indeed, of all encounters, of any kind?

It all stems from the same thing - which is that when we are face to face - and this is what I think is so ironic about Facebook being called Facebook, because we are not face to face on Facebook ... when we are face to face, we are inhibited by the presence of the other. We are inhibited from aggression by the presence of another face, another person. We're aware that we're with a human being. On the Internet, we are disinhibited from taking into full account that we are in the presence of another human being.

We are not as strong as technology's pull.

Technology doesn't just do things for us. It does things to us, changing not just what we do but who we are.
