I repeat my solemn duty to say that the commonly attributed description of simulacra defined by Baudrillard (in this very meme in fact!) has been twisted by memery. Please read Baudrillard.

EDIT: The meme implies that the real still exists - under Fourth Order Simulation there is only the hyperreal. More real than real.

It's not that the real no longer exists or identifiable, it is that the hyperreal, the realer than real, is the only thing that remains.
