人们一直以矛盾的心理来对待技术进步.一方面,技术进步能提高生活水平,扩大受自然资源匮乏所制约的增长极限.以同样的投入可以生产出数量更多、品种更丰富的商品和劳务.另一方面,许多人都已感受到由技术进步带来的种种变革的威胁.因为在一个不断变化着的世界中,即便大多数人受益,也难免会有一部分人受到损害. People have always treated the advancement of technology in a contradictory way: on the one hand, advances in technology can raise the standard of living and expand the growth limit constrained by the scarcity of natural resources, and with the same inputs, more and more varieties of goods and services can be produced On the other hand, many people are already feeling the threats of the changes brought about by technological advances, because in a changing world, even most people benefit, some people will inevitably be harmed.
