Inspiration, practical application and diffusion of technology through society. (ALVIN TOFFLER)

Technology feeds on itself. Technology makes more technology possible, as we can see if we look for a moment at the process of innovation. Technological innovation consists of three stages, linked together into a self-reinforcing cycle. First, there is the creative, feasible idea. Second, its practical application. Third, its diffusion through society.

The process is completed, the loop closed, when the diffusion of technology embodying the new idea, in turn, helps generate new creative ideas. Today there is evidence that the time between each of the steps in this cycle has been shortened.

Thus it is not merely true, as frequently noted, that 90 percent of all the scientists who ever lived are now alive, and that new scientific discoveries are being made every day. These new ideas are put to work much more quickly than ever before. The time between original concept and practical use has been radically reduced. This is a striking difference between ourselves and our ancestors. Appollonius of Perga discovered conic sections, but it was 2000 years before they were applied to engineering problems. It was literally centuries between the time Paracelsus discovered that ether could be used as an anaesthetic and the time it began to be used for that purpose.

Even in more recent times the same pattern of delay was present. In 1836 a machine was invented that mowed, threshed, tied straw into sheaves and poured grain into sacks. This machine was itself based on technology at least twenty years old at the time. Yet it was not until a century later, in the 1930’s, that such a combine was actually marketed. The first English patent for a typewriter was issued in 1714. But a century and a half elapsed before typewriters became commercially available. A full century passed between the time Nicholas Appert discovered how to can food and the time canning became important in the food industry.

Today such delays between idea and application are almost unthinkable. It is not that we are more eager or less lazy than our ancestors, but we have, with the passage of time, invented all sorts of social devices to hasten the process. Thus we find that the time between the first and second stages of the innovative cycle—between idea and application—has been cut radically. Frank Lynn, for example, in studying twenty major innovations, such as frozen food, antibiotics, integrated circuits and synthetic leather, found that since the beginning of this century more than sixty percent has been slashed from the average time needed for a major scientific discovery to be translated into a useful technological form. Today a vast and growing research and development industry is consciously working to reduce the lag still further.

But if it takes less time to bring a new idea to the marketplace, it also takes less time for it to sweep through the society. Thus the interval between the second and third stages of the cycle—between application and diffusion—has likewise been sliced, and the pace of diffusion is rising with astonishing speed. This is borne out by the history of several familiar household appliances. Robert B. Young at the Stanford Research Institute has studied the span of time between the first commercial appearance of a new electrical appliance and the time the industry manufacturing it reaches peak production of the item.

Young found that for a group of appliances introduced in the United States before 1920—including the vacuum cleaner, the electric range, and the refrigerator—the average span between introduction and peak production was thirty-four years. But for a group that appeared in the 1939-1959 period—including the electric frying pan, television, and washerdryer combination—the span was only eight years. The lag had shrunk by more than 76 percent. “The post-war group,” Young declared, “demonstrated vividly the rapidly accelerating nature of the modern cycle.”

The stepped-up pace of invention, exploitation, and diffusion, in turn, accelerates the whole cycle still further. For new machines or techniques are not merely a product, but a source, of fresh creative ideas.

Each new machine or technique, in a sense, changes all existing machines and techniques, by permitting us to put them together into new combinations. The number of possible combinations rises exponentially as the number of new machines or techniques rises arithmetically. Indeed, each new combination may, itself, be regarded as a new supermachine.

The computer, for example, made possible a sophisticated space effort. Linked with sensing devices, communications equipment, and power sources, the computer became part of a configuration that in aggregate forms a single new super-machine—a machine for reaching into and probing outer space. But for machines or techniques to be combined in new ways, they have to be altered, adapted, refined or otherwise changed. So that the very effort to integrate machines into super-machines compels us to make still further technological innovations.

It is vital to understand, moreover, that technological innovation does not merely combine and recombine machines and techniques. Important new machines do more than suggest or compel changes in other machines—they suggest novel solutions to social, philosophical, even personal problems. They alter man’s total intellectual environment—the way he thinks and looks at the world.

We all learn from our environment, scanning it constantly—though perhaps unconsciously—for models to emulate. These models are not only other people. They are, increasingly, machines. By their presence, we are subtly conditioned to think along certain lines. It has been observed, for example, that the clock came along before the Newtonian image of the world as a great clock-like mechanism, a philosophical notion that has had the utmost impact on man’s intellectual development. Implied in this image of the cosmos as a great clock were ideas about cause and effect and about the importance of external, as against internal, stimuli, that shape the everyday behavior of all of us today. The clock also affected our conception of time so that the idea that a day is divided into twenty-four equal segments of sixty minutes each has become almost literally a part of us.

Recently, the computer has touched off a storm of fresh ideas about man as an interacting part of larger systems, about his physiology, the way he learns, the way he remembers, the way he makes decisions. Virtually every intellectual discipline from political science to family psychology has been hit by a wave of imaginative hypotheses triggered by the invention and diffusion of the computer—and its full impact has not yet struck. And so the innovative cycle, feeding on itself, speeds up.

If technology, however, is to be regarded as a great engine, a mighty accelerator, then knowledge must be regarded as its fuel. And we thus come to the crux of the accelerative process in society, for the engine is being fed a richer and richer fuel every day.
