Alvin Toffler writes about the fact that technology is advancing much faster today than ever before in history. The symbols of technology are no longer factory 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 always 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 furnace centuries later. Moreover， technology includes techniques， or ways to do things， as well as the machines that may or may not be necessary to apply 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 And the assembly line —— the organization of large numbers of men to carry out simple repetitive functions —— is outdated.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 change 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 BC 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 tan half that speed. It was probably not until the 1880s 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
