The last 150 years have amounted to such a cavalcade of wonders and technological marvels that we’ve literally programmed ourselves to expect it will continue indefinitely. This sequence of events — the telephone, the light bulb, electricity in every home, airplanes, motion pictures, television, the computer, and thousands of other conveniences to human life—programmed us to think there’s an endless supply of technological magic that can overcome anything. I think we’re heading into a time-out from technological progress as we’ve known it—and by that, I mean just the way I’ve described it, the expectation of endless magic. And I think that will come as an enormous shock to our culture.
