Hawking’s black hole information paradox arises when the formation and subsequent evaporation of a black hole is examined in the context of quantum theory. In a gravity theory with a gauge theory dual, the paradox must be resolved in favor of unitary evolution. The challenge is then to implement unitarity on the gravity side and a key issue, which is at the center of the recent debate on firewalls, is whether this requires giving up the equivalence principle. For a black hole formed in a generic pure quantum state, we argue that a typical infalling observer will see no drama on their way to the stretched horizon and a proposal is made for an approximate interior effective field theory description where this conclusion holds until the observer approaches the black hole singularity.
