The article talks about how confusing Markdown can get. I understand, but HTML is *much* more confusing when it comes to creating technical articles. These days we are going to see more and more markdown with the advent of AI. Markdown works really we with AI because it reduces the number of tokens required for the same amount of information vs HTML.

Yes fully agreed, markdown is going to win by far just because of tokens and AI. The only thing I think right now that should be advanced, is plugins/custom components for markdown, like .mdx, etc token efficient ways of visualizing things in various ways, or custom interactive components, etc.
