  In this note I elaborate on some features of a recent proposal of Papadodimas
and Raju for a CFT description of the interior of a one-sided AdS black hole in
a pure state. I clarify the treatment of 1/N corrections, and explain how the
proposal is able to avoid some of the pitfalls that have disrupted other recent
ideas. I argue however that the proposal has the uncomfortable property that
states in the CFT Hilbert space do not have definite physical interpretations,
unlike in ordinary quantum mechanics. I also contrast the "state-dependence" of
the proposal with more familiar phenomena, arguing that, unlike in quantum
mechanics, the measurement process (including the apparatus) in something like
the PR proposal or its earlier manifestations cannot be described by unitary
evolution. These issues render the proposal somewhat ambiguous, and it seems
new ideas would be needed to make some version of it work. I close with some
brief speculation on to what extent quantum mechanics should hold for the
experience of an infalling observer.
