Attention as a Scarce Resource

For most of industrial history the binding constraint on media was distribution. There were only so many printing presses, channels and hours in the day.

在工业时代的大部分历史里，媒体受制于的瓶颈是分发。印刷机、频道和一天中的小时数都是有限的。

Digital networks removed that constraint almost entirely, and something else became scarce. The bottleneck is no longer the supply of content but the human capacity to attend to it.

数字网络几乎完全移除了这一限制，于是另一样东西变得稀缺了。瓶颈不再是内容的供给，而是人集中注意力的能力。

Business models adapted accordingly. When attention is the scarce good, the objective shifts from satisfying users to retaining them. Content is then optimised not for value but for frictionless continuation.

商业模式随之调整。当注意力成为稀缺品，目标就从「让用户满意」转向「留住用户」。内容不再为价值而优化，而是为「让人毫无阻力地继续看下去」而优化。

Recognising this asymmetry is the beginning of resistance. Anyone who understands that their attention is being harvested can begin to spend it deliberately.

意识到这种不对称，是抵抗的开始。任何明白自己的注意力正在被收割的人，都可以开始有意识地支配它。

The consequences reach well beyond wasted hours. Attention is the raw material of learning, of friendship and of careful judgement; a mind trained to switch every twenty seconds becomes worse at all three.

后果远不止浪费掉几个小时。注意力是学习、友谊和审慎判断的原材料；一颗被训练成每二十秒切换一次的大脑，在这三件事上都会变差。

Some remedies are personal — turning off notifications, leaving the phone in another room, deciding in advance what a session is for. Others are collective and far harder: building products that are judged by whether users are better off, not merely by how long they stay.

有些补救是个人层面的 —— 关掉通知、把手机放到另一个房间、事先想清楚这一次打开是为了什么。另一些则是集体的、也难得多：做出这样的产品 —— 衡量它的标准是用户是否因此过得更好，而不只是他们停留了多久。
