With the developement of the techniques of effective field theory, one can recognize that the quantum theory of general relativity is not problematic but behaves in the same way as other effective field theories. This tells us that the conventional wisdom - that there is no quantum theory of gravity - is false. The effective field theory treatment allows us to explore the structure and the limits of quantum general relativity. In particular, one can see how to extract reliable quantum predictions from general relativity at ordinary scales.
