AI is here to stay. If used right, chances are it will make us all more productive. That, on the other hand, does not mean it will be a good investment.
这是全文最核心的论断：技术有用不等于投资有利可图。历史反复证明，革命性技术（如铁路、互联网）往往在初期引发过度投资和泡沫，最终造福社会，却让早期投资者血本无归。AI也难逃此律，生产力提升的公共收益与资本逐利的私人回报之间存在根本错位。
Someone who builds premium dating apps, let's say, might use AI coding tools to create in one day what used to take three days. That means the worker is more productive. The worker's employer, spending the same amount of money, can now get more output. So then will the employer want more employees or fewer?
大多数人认为AI提高生产力必然带来就业增长，但作者提出了一个反直觉的问题：当工人效率提高，雇主可能会选择减少而非增加员工。这种质疑挑战了'技术进步-就业增长'的线性因果关系假设。
