The perturbative non-renormalizability of the Einstein-Hilbert action is often taken as a hint that a quantum field theory of gravity should be non-perturbative, and asymptotically safe quantum gravity is often viewed as an example. In this talk, I will present indications that asymptotically safe quantum gravity with matter is instead near perturbative and I will discuss implications, both for the control of approximations as well as for the relation of Euclidean to Lorentzian signature settings.
