Every one of today’s smartphones has thousands of times more processing power than the computers that guided astronauts to the moon. And if Moore’s law – the theory that computing capacity doubles roughly every two years – continues to be accurate, tomorrow’s computers will be even stronger.
与当年指导宇航员登月的计算机相比,今天每一部智能手机的数据处理能力都要胜出几千倍。如果摩尔定律依旧准确,未来计算机将更加强大。根据摩尔定律,计算能力大约每两年增加一倍
But Americans today dream less often of feats that computers will help us to accomplish; more and more we have nightmares about computers taking away our jobs. The optimism that many felt in the 1960s over labour-saving technology is giving way to a fearful question: will your labour be good for anything in the future? Or will you be replaced by a machine?
但今日的美国人较少再幻想计算机将帮人类实现丰功伟绩,而是越来越恐惧计算机将夺走我们的工作。20世纪60年代时,许多人对节省人力的技术抱持乐观态度,而今这种乐观已让位于一个可怕的问题:你的劳动在未来有利用价值吗?或者是,你会被机器取代吗?
Fear of replacement is not new. Fifteen years ago American workers were worried about competition from cheaper Mexican substitutes. In 1992 US presidential candidate Ross Perot predicted that a “giant sucking sound” would be heard along the country’s southern border as soon as the North American Free Trade Agreement was signed.
