Alvin Toffler writes about the fact that technolo-
gy is advancing much faster today than ever before in
history. The symbols of technology are no longer facto-
ry smokestacks or assembly lines. As we are headed for
the future, the pace will quicken still further.
 
 
THE FANTASTIC SPURT IN TECHNOLOGY
 
 
A. Toffler
 
To most people the term  technology conjures up images of smoky steel 
mills or noisy machines. Perhaps the classic representation of technology is
still the assembly line created by Henry Ford half a century ago and made
into a social symbol by Charlie Chaplin in Modern Times . This symbol,
however, has always been inadequate and misleading, for technology has al-
ways been more than factories and machines. The invention of the horse
collar in the middle ages led to major changes in agricultural methods and
was as much a technological advance as the invention of the Bessemer fur-
nace centuries later. Moreover, technology includes techniques, or ways to
do things, as well as the machines that may or may not be necessary to ap-
ply them. It includes ways to make chemical reactions occur, ways to breed
fish, plant forests, light theaters, count votes or teach history.
The  old  symbols of technology are even more  misleading  today,  when
the most advanced technological processes are carried out far from assembly
lines or blast furnaces. Indeed, in electronics, in space technology, in most
of the new industries, quiet and clean surroundings are characteristic-- even
sometimes essential. And the assembly line - the organization of large numbers
of men to carry out simple repetitive functions - is outdated. It is time for
our symbols of technology to change - to catch up with the quickening
in technology itself .
This acceleration is frequently dramatized by a brief account of the progress
in transportation. It has been pointed out, for example, that in 6000 BC
the fastest transportation available to man over long distances was the camel
caravan, averaging eight miles per hour (mph) . It was not until about 1600
when the chariot was invented that the maximum speed was raised to
roughly twenty miles per hour.
So impressive was this invention, so difficult was  it  to  exceed this  speed
limit, that nearly 3,500 years later, when the first mail coach began operating
in England in 1784, it averaged a mere ten mph. The first steam locomotive,
introduced in 1825, could have a top speed of only thirteen mph and
the great sailing ships of the time labored along at less than half that speed.
It was probably not until the 1880's that man, with the help of a more
advanced steam locomotive, managed to reach a speed of one hundred
mph. It took the human race millions of years to attain that record.
It  took only  fifty-eight  years, however, to go four times  that fast, so  
that by 1938 men in airplanes were traveling at better than 400 mph. It
took a mere twenty-year flick of time to double the limit again. Arid by the
1960's rocket planes approached speeds of 4,000 mph. and-men in space
capsules were circling the earth at 18,000 mph.
Whether  we  examine  distances  traveled,  altitudes  reached,  or  minerals 
mined, the same accelerative trend is obvious. The pattern, here and in a
thousand other statistical series, is absolutely clear and unmistakable.
Thousands of years go by, and then, in our own times, a sudden bursting
of the limits, a fantastic spurt forward.
The  reason for this is that  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 tech-
nology 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  al  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 the first and second stages of
cycle - between idea and application-- has been radically reduced. the This
is a striking difference between ourselves and our ancestors. 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.
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. For example, the refrigerator
was introduced in the United States before 1920, yet its peak production
did not come until more than thirty years later. However, by 1950- in only a
few years - television had grown from a laboratory novelty to the biggest
part of show business. So the interval between the second and third stages
of the cycle - between application and diffusion - has likewise been cut, and
the pace of diffusion is rising with astonishing speed.
The  stepped-up  pace  of   invention,  application   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.
