I think OP has envisioned a situation half way between what we now have and what will soon be the actual reality and that his idea will just be quickly skipped over.

I don't think website design will go away, but I do expect that people will soon be ordering products and booking holidays through AI chats instead of doing it themselves, which will require the kind of manifests he's talking about, but will skip the UI layer completely.
