I meant the "block editor" aspect, like how individual chunks of text and images can be independently selected and moved around or even shared with their own URL.

I've long believed some system like that could and should some day replace even HTML and the web, and that it'll only happen if the Semantic Web ever takes off in a big way where chunks of stuff are "typed" (like a Type-Safe Web). Even Tim Berners Lee has been dreaming of this for decades, but the world is still stuck in HTML-land for the foreseeable future.
