人们对关于他们自己可知的事情一无所知。突发新闻：你自己的每个视频源都包含你的心跳和呼吸频率的信号。这些只是摄像头捕捉到的众多生物识别信号中的几个。

就在前几天，我让 Claude 给我写一个通过网络摄像头显示我的心率和呼吸频率的应用程序。它毫不费力地照做了。

People have no idea what is knowable about them. Newsflash: every video feed of yourself includes a signal of your heartbeat and breathing rate. These are just a few of the many biometrics a camera picks up.

Just the other day I asked Claude to code me an app that shows my heart rate and breathing rate via my web cam. It complied without issue.
