The current global revolution is based on rapid technological advances that have dramatically decreased the cost of creating, finding, and transmitting information. Computing power doubled roughly every 18 months for 30 years, and, by the beginning of the twenty-first century, it cost one-thousandth of what it did in the early 1970’s.
当前的全球革命的基础是快速的技术进步，它们极大地降低了创造、寻找和传播信息的成本。30年来，计算能力每隔18个月就能翻一番，21世纪初，计算成本只有20世界70年代的千分之一。如果汽车的价格减半的速度和半导体一样快，那么如今花5美元就能买辆车。
