As the author of a content management system I made with the idea to democratize internet content creation, I've had a lot of the same thoughts that the author brings up here. I've always thought that even learning Markdown was a bridge to far when it comes to empowering non-technical users however. In my experience it's best just to supply tooling similar to Word where you have buttons for things like lists and bolding. Using Markdown as the format itself is something I will agree with though.

Another thought I had is that local AI could most definitely play a part in helping non-technical users create the kind of content they want. If your CMS gives you a GPT-like chat window that allows a non-technical user to restyle the page as they like, or do things like make mass edits - then I think that is something that could help some of the issues mentioned here.
