The brain, the computer, and the economy: all three are devices whose purpose is to solve fundamental information problems in coordinating the activities of individual units – the neurons, the transistors, or individual people. As we improve our understanding of the problems that any one of these devices solves –&#160;and how it overcomes obstacles in doing so – we learn something valuable about all three.
大脑、计算机和经济，这三者均是以通过个体单元——神经元、晶体管或个人——的合作和行为解决基本信息问题的机制。只要我们对这三者之中的任何一者如何解决问题——以及如何克服解决问题中出现的障碍——的理解有了突破，都能将其推广到其他两者。
