  Computations in the calculable small coupling regime of string theories and
the general consensus that no new physics has to be invoked in continuing to
the large coupling (black hole) regime, suggest the following picture. Quantum
states are not black holes even if energy distributions would suggest so. Black
holes appear as macrostates, i.e. with the same procedure that blures the
quantum coherence of microstates. It is also discussed how a spacetime
description - and thus geometry, causal properties and event horizons - may
stem from decoherence in the pregeometric approach represented by string
theories.
