While Typst appears to be popular, I think that TeXmacs, https://www.texmacs.org/, which is a program independent from both TeX and Emacs, is the kind of program that we need for writing: a fully WYSIWYG, fully structured document preparation system, in which you edit the structure of your document in a WYSIWYG way. When editing the structure on-screen, the user has no need to be aware that is doing so, as it looks like they are editing a text document; at the same time, the TeXmacs editor will guide the user to keeping a structured document.
