I use VimWiki[0]. There's a possibility it will go away, but I doubt it. There's a possibility both vim and neovim will go away, but I doubt it.
It stores everything as Markdown files. Should Markdown ever go away, it's all still very readable plain text files. I use UTF-8. Perhaps that'll go away at some point?
I version everything with git, I doubt git will fully go away, but I'm ok migrating to a different VCS if need be.
