> For years, I had been building what technologists and lifehackers call a “second brain.” The premise: capture everything, forget nothing.

Is that really what people think of when they hear "second brain"? For me, it doesn't mean "capture everything", it just means "capture things where you can retrieve them later", but setting out to "capture everything" sounds both like a nightmare for capturing, but as the author seemingly found out, it also seems like a nightmare to maintain.

The personal knowledge management systems turned into a mausoleum of old selves that replaced thinking rather than enhancing it.
