I will argue that novel (highly nonclassical) quantum extremal surfaces play a crucial role in reconstructing the black hole interior even for isolated, single-sided, non-evaporating black holes (i.e. with no auxiliary reservoir). Specifically, any code subspace where interior outgoing modes can be excited will have a quantum extremal surface in its maximally mixed state. Therefore, the reconstruction of interior outgoing modes is always exponentially complex. As an application, I will show how these quantum extremal surfaces geometrize the exponential complexity of the holographic dictionary as discussed by Bouland, Fefferman, and Vazirani.
