As mentioned in the linked comments, I think just using something like Tinker Writer Deck ( https://tinker.sh/ ) or even just using something like focuswriter in a slimmed down modern OS, is a much easier approach - because of much easier interfacing with the outside world (and used hardware). That way you can use rather normal stuff like rsync to backup your work through an actual ethernet or WiFi connection.

But I must admit, I really like the sentiment of the article :⁠-⁠)
