The origin of the hierarchical spectrum of quark and lepton masses observed in Nature is one of the long-standing open questions in particle physics. The recent hints of non-standard phenomena in low-energy flavour-changing processes have opened new directions in model building which might address this issue, and possibly connect it to the more general search for physics beyond the Standard Model. In this talk I will critically review these hints, highlighting some of these new directions they might suggest, and discussing their possible future implications.
