I’m scared of cults and not ever being truly enlightened is a risk I’m willing to take. Maybe one day.

Seriously though, in terms of longevity, where I want the dependencies of my system to last for the rest of my life and to be easily installed on as many machines throughout the rest of my life, SQLite (and pure Python for the wrapper, using only the std lib) seem like good bets. Better bets than emacs and org-mode, perhaps not, but certainly without the baggage of being bound to a text editor.

EDIT: just clicked the link, lol.
