Abstruct: Tiny neutrino masses and large lepton flavor mixing angles are expected to originate from new physics beyond the standard model (SM) of particle physics, but which kind of new physics is
most likely has been an open question. This talk is intended to
highlight the canonical seesaw mechanism as a favorite, given
the lesson learnt from historical roles that lepton flavors have
played in the development of the SM. Some personal opinions are added on pains and gains in introducing new degrees of freedom.
