I think expansive space colonization would reduce the risk asymptotically, since itโs unlikely for all of a large number of very distant civilizations to go extinct around the same time. The more distant the civilizations, the more roughly independent their risks should be. And the more civilizations there are, the more likely at least one is around at any time.
