　　To live in the United States today is to gain anappreciation for Dahrendorf’s assertion thatsocial change exists everywhere. Technology, theapplication of knowledge for practical ends, is amajor source of social change.

　　Yet we would do well to remind ourselves that technology is a human creation; it does not existnaturally.A spear or a robot is as much a cultural as a physical object. Until humans use aspear to hunt game or a robot to produce machine parts, neither is much more than a solidmass of matter. For a bird looking for an object on which to rest, a spear or robot serves thepurpose equally well. The explosion of the Challenger space shuttle and the Russian nuclearaccident at Chernobyl drive home the human quality of technology;they provide cases in whichwell-planned systems suddenly went haywire(变得混乱) and there was no ready hand to setthem right. Since technology is a human creation, we are responsible for what is done with it. Pessimists worry that we will use our technology eventually to blow our world and ourselves topieces. But they have been saying this for decades. and so far we have managed to surviveand even flourish. Whether we will continue to do so in the years ahead remains uncertain. Clearly, the impact of technology on our lives deserves a closer examination.

　　Few technological developments have had a greater impact on our lives than the computerrevolution. Scientists and engineers have designed specialized machines that can do thetasks that once only people could do.There are those who assert that the switch to aninformation-based economy is in the same camp as other great historical milestones, particularly the Industrial Revolution. Yet when we ask why the Industrial Revolution was arevolution, we find that it was not the machines. The primary reason why it was arevolutionary is that it led to great social change. It gave rise to mass production and, through mass production, to a society in which wealth was not confined to the few.

　　In somewhat similar fashion, computers promise to revolutionize the struccure of American fife, particularly as they free the human mind and open new possibilities in knowledge andcommunication. The Industrial Revolution supplemented and replaced the muscles of humansand animals by mechanical methods. The computer extends this development to supplementand replace some aspects of the mind of human beings by electronic methods. n is thecapacity of the computer for solving problems and making decisions that represents itsgreatest potential and that poses the greatest difficulties in predicting the impact on society.
