With Joplin, you can easily archive as Markdown+FrontMatter and that format will still be readable 40 years from now with text and metadata included.
Additionally, in case you forgot to make a backup, and 40 years later all traces of Joplin have disappeared from earth and you can't find an old version of the app, the backend is a simple SQLite database, so you can do `SELECT * FROM notes` and get your content back.
