Non-reciprocal interactions (NRIs) are quite natural among  higher organisms including humans, as we all know that the way two  humans act towards each other does not derive from a mutual  translationally symmetric ``interaction potential'' that gives rise to  action=-reaction. It is, however, a remarkably surprising that NRIs  can exist at the microscopic scale among brain-less particles, in  particular enzymes, when they are catalytically or metabolically  active, i.e. under non-equilibrium conditions. In this Colloquium, I  will introduce the topic and discuss some of its non-trivial  consequences, following the developments in the field over the last  decade. In particular, we discuss how non-reciprocal active matter can  provide a paradigm within which we can understand how it may have been  possible to form self-organized metabolic cycles at the early stages  of life formation in a fast and robust manner.
