Or... anything, honestly.  We're humans. Our understanding and perception
of the universe changes daily.  I don't think it's unreasonable to accept
that any description of the universe, input by a human, will reflect the
fundamental reality that was was encoded might be wrong.  I don't really
buy the argument that RDF is somehow less capable of "succinctly
articulating knowledge" compared to anything else.  "All models are wrong.
 Some are useful."

(information vs. non-information resource) and I think that most (sane,
pragmatic) practitioners would consider that "linked data", as well.  Given
the fact that schema.org is so easily mapped to RDF, I think this argument
is going to be so polluted (if it isn't already) that it will eventually
have to evolve to a far less academic position.

each serialization (besides RDF/XML) works extremely well for specific
purposes:

Turtle is great for writing RDF (either to humans or computers) and being
able to understand what is being modeled.

n-triples/quads is great for sharing data in bulk.

json-ld is ideal for API responses, since the consumer doesn't have to know
anything about RDF to have a useful data object, but if they do, all the
better.
