Quantum cosmology can be seen as the executive arm of quantum gravity. It provides the best chance for observations and tests of the whole theory, thereby holding enormous power to decide about its ultimate fate. This power is often undercut by the weakly built relationship with the legislative branch of constructing the fundamental theory, making it easily evadable. Fortunately, the ties are being strengthened by ongoing research, as is the observational judiciary. With a long-term perspective, quantum cosmology and quantum gravity thus seem on a promising and scientifically sustainable way.
