本周推荐:《一件T恤的全球经济之旅》
作者:皮厄特拉·里佛利
译者:王海峰、吴恒源
推荐:小编1号
每年仅仅中国大陆就有近万本图书被推向市场,而书的名字是吸引读者视线的第一步,就比如这本书。无容置疑这是一个好的名字,以至于你可以搜到两本一模一样名字的书。注意看作者和副标题,本书是较新的一版,写作风格也是表熟悉的味道,在宏观历史背景介绍和当下接触到的具体的人的日常穿插进行,故事感还是比较强的。
站在2025年看这本2016年翻译的书,短短几年已经有物是人非的历史时间隔离的感觉了。不禁让我感慨万千,同时也让我警惕自身与广大民众的脱节:计算机、软件、互联网、AI的密切接触让我能够快速接纳和跟上(可能是)人类社会最前沿的节奏,而中国大流这片土里上可能还有超过10亿人尚未看到这个未来。他们要怎么办?
历史总是寥寥几笔,勾勒千万普通人一生。
