  It is an exciting time for flavor physics. In this talk, I discuss recent
topics in baryogenesis and leptogenesis in light of new data, and implications
in B and neutrino physics. I also discuss current situation of grand unified
theories concerning coupling unification, proton decay, and indirect
consequences in lepton flavor violation and B physics. I explain attempts to
understand the origin of flavor based on flavor symmetry, in particular
"anarchy" in neutrinos.
