I am never sure which notes I am going to reference again. Most of my daily notes go unread forever. But occasionally, that seemingly trivial thing that I jotted down in a meeting turns out to be _very_ important. I have AI assistants that take notes for me too, but somehow I can’t stop taking notes in meetings - and occasionally this has saved me (note taker bugged out).
Daily notes are also where I do a lot of scratch pad thinking, and occasionally those come in handy as well.
