Flavour physics provides some of the most stringent tests of the Standard Model and a powerful indirect probe of new physics. Precision studies of quark transitions have revealed a striking pattern of masses, mixings, and CP violation that remains unexplained by current theory, while persistent tensions in key observables continue to attract attention. In this talk, I will review the present status of flavour physics, highlighting both the successes of the Standard Model and the puzzles that persist. I will then discuss how future progress, driven by increasingly precise measurements and theoretical developments, may provide crucial clues toward a deeper understanding of the flavour sector and its role in fundamental physics.
