  We discuss the black hole information problem, including the recent claim
that unitarity requires a horizon firewall, emphasizing the role of decoherence
and macroscopic superpositions. We consider the formation and evaporation of a
large black hole as a quantum amplitude, and note that during intermediate
stages (e.g., after the Page time), the amplitude is a superposition of
macroscopically distinct (and decohered) spacetimes, with the black hole itself
in different positions on different branches. Small but semiclassical observers
(who are themselves part of the quantum amplitude) that fall into the hole on
one branch will miss it entirely on other branches and instead reach future
infinity. This observation can reconcile the subjective experience of an
infalling observer with unitarity. We also discuss implications for the nice
slice formulation of the information problem, and to complementarity.
