Paper is just too inconvenient to use for long term storage and revisiting imo. It's better suited as a transitive storage medium, either for short lived stuff like tasks, checklists, or acting as a writing inbox that you later capture into a digital medium.

Even with the capture downside, I don't think that I can do away with paper and pen. There's something invigorating about using paper that no keyboard or screen could replicate. More in touch with your brain and with your own words, that your feelings flow better into the ink. It is something that makes me enjoy writing.

I've considered e-ink devices in the past but I don't see much value from them. They're a fancier way to draft things at best, in my case, and a worse PKMS/Todo list if anything compared to dedicated tools. I'm paying for an extra device that gives me a bunch of things I won't use, anyways.
