It was Thucydides who called war “the human thing” – the only definition the Greek historian was willing to offer. War and humanity have evolved together from the beginning. The problem is that 21st-century technology is changing our understanding of war in deeply disturbing ways. “The human [element] is becoming the weakest link,” in the words of an unclassified report from 2003 by the Defense Advanced Research Projects Agency (Darpa), the Pentagon body responsible for the development of technologies for the US military.
修昔底德(Thucydides)称战争是“人类本性”,这是这位古希腊历史学家愿意提供的唯一定义。从一开始,战争与人性就交织在一起不断演变。问题是,21世纪的科技正在以极其令人不安的方式改变着我们对战争的理解。美国国防高级研究计划局(DARPA)在2003年的一份公开报告中指出:“人类(因素)正在成为最薄弱的环节。”DARPA是五角大楼负责美军技术开发的机构。
