Abstract. The de Sitter (dS) entropy bound gives the maximal number of e-folds that non-eternal inflation can last before violating the thermodynamical interpretation of dS space. This semiclassical argument is the analogue, for dS space, of the Black-Hole information paradox. After reviewing the techniques that have recently allowed to address successfully the latter, namely the so-called island formula, I will present their application to the to study the dS entropy bound. This calculation suggests that, at least in the toy model that I consider, the semiclassical expectation should be modified in such a way that the entropy bound might actually not be present.
