As a result, the modern world is increasingly populated by intelligent robots whose presence we barely notice but whose universal existence has removed much human labor. And thanks to the continual miniaturization of electronics and micro-mechanics, there are already robot systems that can perform some kinds of brain and bone surgery with far greater precision than highly skilled physicians can achieve with their hands alone. But if robots are to reach the next stage of laborsaving utility, they will have to be able to make at least a few decisions for themselves. Despite a spell of initial optimism in the 1960s and 1970s when it appeared that transistor circuits and microprocessors might be able to copy the action of the human brain by the year 2010, researchers lately have begun to extend that forecast by decades if not centuries.
问答题
第二天清早，她起早出了门。她走进批发行商业区，但是每当她走到一个商号，打算进去申请工作时，她的勇气就消失了。她心里骂自己是胆小鬼，所以她继续往前走，走了又走，最后终于走进了一家商号。结果还是老样子。她出来时感到命运在和她作对，因此一切努力都是徒劳的。 她不知不觉中来到一个大商场，门口有成群的顾客。这些立刻使她改变了想法。她原先就是打算到这里来买新衣服的。现在为了解愁，她决定进去瞧瞧。她很想看看那些外套。有时，一个人尽管想买东西，可是又因心里拿不定主意，所以在心里不断掂量权衡。世界上再没有比这种中间状态更令人愉悦了。
