Depends on which war we are talking about. Personal writing? Professional writing? Machine-readable? For personal writing, HTML is not really participating, for the rest, mostly yes, even though for AI-tooling markdown seems the preferred language now.

Which opens the question, is there a real advantage in using Markdown with AI instead of HTML? Or did nobody ever tried this?

I also vote for HTML. It’s the only language I can write in which also includes all the metadata I want to include (schema.org and wikidata.org ontologies).

I’m very curious about why I’ve been downvoted. I assumed the HN crowd was tech-savvy enough to know what ontologies are? And one can’t write a blog post in Turtle.
