I completely agree with this take. There's an immense feeling of calm when your digital life revolves around files you completely own. I've managed my entire productivity around a single org-mode file for the bast five years and it perfectly adapts to my needs. Add on top of that syncthing and I have a robust system I can use on mobile that works perfectly for me.

I feel I could leave and come back in 20 years and still use my org-mode productivity file, Emms[1] playlist, verb[2] HTTP request book, etc. exactly the same as I left off. What would my data in Notion, Postman, etc. all look like in 20 years if left unattended?
