Title: Black hole complementarity - the inside view

Abstract: 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 but the challenge is then to implement unitarity on the
gravity side. 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.
