I’m not sure that I buy all the points made. I can imagine an AI centric CMS where the technical interface (implement this site on MySQL, host it there, use Next.js, etc) is distinct from the content interface (change store hours) or even the design (change the background).

I have used Wordpress a lot (too much) and came to the view that for most websites it is just overkill. So I built https://harcstack.org and vowed to write all my new sites in actual code.

HTMX to the rescue since you can write server side code in a sensible way and still have quite a dymanic UX.
