  We suggest a mechanism for the emergence of classical dynamical spacetime
from an underlying quantum gravitational system. This is an example of a more
general process, which we name micro-equilibration, and which can be thought of
as local thermalization of entanglement. Applied in the context of the AdS/CFT
correspondence, we propose that this dynamical process underlies generic
evolution towards CFT states whose gravitational dual describes smooth bulk
geometries. Hence contrary to common expectation, such 'geometric' CFT states
are in fact typical in this sense. Correspondingly they can be characterized by
a specific universal entanglement structure resulting from micro-equilibration
of a generic quantum state.
