The LHC runs at 7 and 8 TeV have led to the discovery of the Higgs boson at 125 GeV which will remain as one of the major physics discoveries of our time. Another very important result was the surprising absence of any signals of new physics that, if confirmed in the continuation of the LHC experiments, is going to drastically change our vision of the field. Indeed the theoretical criterium of naturalness required the presence of new physics at the TeV scale. At present the indication is that Nature does not too much care about our notion of naturalness. Still the argument for naturalness is a solid one and one is facing a puzzling situation. We review the different ideas and proposals that are being considered in the theory community to cope with the naturalness problem.
