XML vs JSON LD vs Turtle vs RDFa are largely interchangeable, actually a
red herring ...

Instead of reading XML, understand what is the connotation.  Namely, a
universal format capable of expressing triples via the web of documents.

On top of that we see the giant global graph delivered via the web of
documents (it could be delivered in other ways one day)

The giant global graph (ggg) of data will be highly connected and self
organizing via bottom up emergent design.  Smart data instead of smart
servers.  Ontologies and the like will cluster to give common usage
patterns and allow reuse.

As the web of documents was the discourse of humanity, the web of data (aka
semantic web) will be a giant declarative state machine for humanity,
capable of reading small or large sections.

But reading / browsing is the old way.  We want everyone on the planet to
interact with the sum of human knowledge.  We should think beyond
"browsers", which essentially say, "you can look but you cant touch".

We want the ggg to be dynamic, vital, living

For that you need read and write technology preferably unencumbered

So every human being is a stake holder, not just mediated through monoliths

For that you need the ability to read and write, and a minimal permissions
and identity system, ie i should be able to control WHO can read and write
my part of the GGG

Each part of the layer cake represents ways in which smart data can be a
reflection of the world.  Syntax and technology are largely
interchangeable, but if you get through the connotation behind it, you can
see which aspect of the universal it is trying to model.
