Abstract
Freeman Dyson made these points on Quantum Gravity: (1.) A single graviton cannot be detected, because a measuring two-body apparatus size should be smaller that its gravitational radius. (2.) With no possibility of detecting a single graviton the very concept of Quantum Gravity is practically meaningless. (3.) There is nothing wrong with having separate theories for the large scale (gravity) and for the small scale (quanta). A unification may be in practice (and in principle) unhelpful or even meaningless.
