  Black hole entropy, denoted by N, in (semi)classical limit is infinite. This
scaling reveals a very important information about the qubit degrees of freedom
that carry black hole entropy. Namely, the multiplicity of qubits scales as N,
whereas their energy gap and their coupling as 1/N. Such a behavior is indeed
exhibited by Bogoliubov-Goldstone degrees of freedom of a quantum-critical
state of N soft gravitons (a condensate or a coherent state) describing the
black hole quantum portrait. They can be viewed as the Goldstone modes of a
broken symmetry acting on the graviton condensate. In this picture Minkowski
space naturally emerges as a coherent state of infinite-N gravitons of infinite
wavelength and it carries an infinite entropy. In this paper we ask what is the
geometric meaning (if any) of the classical limit of this symmetry. We argue
that the infinite-N limit of Bogoliubov-Goldstone modes of critical graviton
condensate is described by recently-discussed classical BMS super-translations
broken by the black hole geometry. However, the full black hole information can
only be recovered for finite N, since the recovery time becomes infinite in
classical limit in which N is infinite.
