This paper contains a critique of the standard inflationary account of the origin of cosmological structures from quantum fluctuations in the early universe. This critique can be thought to be purely philosophical in nature, but I prefer to view it, rather, as arising from the need to put the interpretational aspects of the theory -which quite obviously lie at the basis of any comparison with experiments- on the firm grounds required by the unique features of the problem at hand. This discussion is followed by a proposal to complement that treatment to deal with the unsatisfactory aspects of the standard account of the problem, using Penrose's ideas about the quantum gravity induced collapse of the quantum states of matter fields. The formalism developed to carry out this analysis was first introduced in [1] and leads to unexpected predictions and to novel avenues to confront some of the details of the proposal with observations. In my view, this is, therefore, the most promising path towards quantum gravity phenomenology.
