● People are indulging in an illusion whenever they find themselves explaining at acocktail(鸡尾酒) party, say, that they are "in computers," or "in telecommunications," or "inelectronic funds transfer". The implication is that they are part of the high-tech world. Justbetween us, they usually aren't. The researchers who made fundamental breakthroughs in thoseareas are in a high-tech business. The rest of us are  （71） of their work.
