I kinda agree with this, but I think paper is good mostly for drafts because it can quickly become a huge mess when you have a lot of changes to make, especially on diagrams. Plus it's hard to backup and share paper.
And that's not environment friendly ;)
And about To-dos, at least where I work, it was possible to repeat a to-do multiple times in the same notebook and lose others if tasks got interrupted by other tasks (which used to happen much more frequently than it does currently).
