ErikBrynjolfsson and Andrew McAfee of MIT make use of this image in their e-book Race Against the Machine. By the measureknown as Moore s law, the ability to get calculations out of a piece of silicondoubles every 18 months. That growth rate will not last for ever; but otheraspects of computation, such as the capacity of algorithms to handle data, arealso growing exponentially. When such a capacity is low, that doubling does notmatter. As soon as it matters at all, though, it can quickly start to matter alot. On the second half of the chessboard not only has the cumulative effect ofinnovations become large, but each new iteration of innovation delivers atechnological jolt as powerful as all previous rounds combined.
麻省理工学院的埃里克布伦乔尔森和安德鲁麦克菲在他们的电子书《与机器赛跑》中引用了以上这个例子。根据众所周知的摩尔定律,从一片硅片中得到计算的能力每18个月翻一番。这种增长的速率不会永远保持下去;但是,计算机在其他方面的能力,如处理数据的算法,也在成倍地增长。当这种能力处于低水平时,翻番起不了多大的作用。不过,一旦它开始发挥作用的时候,它能迅速地影响许多事物。棋盘的下半部分不仅仅是创新的累计效应在增强,而且每一项新的创新都带来某种技术方面的突飞猛进,其能量如同以前所有技术加起来那么强大。
