Does that imply that Maldacena rejects the holographic universe idea (the versions that claim that the information content of a black hole is bounded by the surface of its event horizon)?
To the contrary, his ideas are based on holographic scaling. The question of how exactly information escapes a black hole remains open. The wormhole work concerns pieces of that larger puzzle, but does not offer a comprehensive solution.
I thought the idea of the holographic universe comes down to the information content of the black hole approximating the information content of a surface, not a volume. Why would anything have to come out of the black hole if you think that?
