Looking to the Future When a magazine for high-school students asked its readers what life would be like in twenty years, they said. Machines would be run by solar power. Buildings would rotate so they could follow the sun to take maximum advantage of its light and heat. Walls would "radiate light" and "change color with the push of a button." Food would be replaced by pills. 1 Cars would have radar. Does this sound like the year 2020 2 The future is much too important to simply guess about the way the high school students did, so experts are regularly asked to predict accurately. 3 But can they One expert on cities wrote= cities of the future would not be crowded, but would have space for farms and fields. People would travel to work in "airbuses", large all-weather helicopters carrying up to 200 passengers. When a person left the airbus station he could drive a coin-operated car equipped with radar. The radar equipment of cars would make traffic accidents "almost unheard of". Does that sound familiar If the expert had been accurate it would, because he was writing in 1957. His subject was "The city of 1982". If the professionals sometimes sound like high-school students, it’s probably because future study is still a new field. But economic forecasting, or predicting what the economy will do, has been around for a long time. It should be accurate, and generally it is. But there have been some big mistakes in this field, too. 4 In October of that year, the stock market had its worst losses ever, ruining thousands of investors who had put their faith in financial foreseers. 5 In 1957, H.J. Rand of the Rad Corporation was asked about the year 2000. "Only one thing is certain, " he answered. "Children will have reached the age of 43. " A. By carefully studying the present, skilled businessmen scientists and politicians are supposedly able to figure out in advance what will happen. B. School would be taught "by electrical impulse while we sleep". C. One forecaster knew that predictions about the future would always be subject to significant errors. D. In early 1929, most forecasters saw an excellent future for the stock market. E. Everyone may look to the future for it is always promising. F. Actually, the article was written in 1958 and the question was, "What will life be like in 19787"
