Recent developments have called into question the validity of the weak
cosmic censorship conjecture — which roughly forbids singularities from
developing outside of event horizons in generic spacetimes — in
classical General Relativity. In this talk I will present evidence using
holography that at least some version of weak cosmic censorship should
still be valid in the classical limit of quantum gravity in AdS. In
particular, I will argue that consistency of the AdS/CFT dictionary in
general, and of the holographic entanglement entropy entry in
particular, implies that trapped surfaces lie behind event horizons.
