Just because it's possible in theory doesn't make it a good idea. In org-mode, anything that isn't plaintext is quite painful to set up and to maintain, at least until you've memorized two dozen arcane key chords. I would love for Emacs to get a Notion-like UI (still with plaintext underneath obviously) one day but until then, I'm okay with people using the best tool for the job, which isn't a text editor.

(I'm an enthusiastic org-mode user, by the way.)
