Economist的这篇文章http://www.economist.com/node/21553017很有意思。

一句话点中3D打印的要害：

The geography of supply chains will change. An engineer working in the middle of a desert who finds he lacks a certain tool no longer has to have it delivered from the nearest city. He can simply download the design and print it.

关于制造业 vs 服务业：

They spend billions backing the new technologies which they, in their wisdom, think will prevail. And they cling to a romantic belief that manufacturing is superior to services, let alone finance.

The lines between manufacturing and services are blurring. Rolls-Royce no longer sells jet engines; it sells the hours that each engine is actually thrusting an aeroplane through the sky.

越来越喜欢读Economist了，语言简单明了，废话少。

第三次工业革命可能让tg有点吃惊，信息革命可不止是替代了邮局那么简单。
