The Fermi Paradox is interesting to me. I know something about nucleosynthesis, but an not an expert. I'm not at all clear on this claim that most heavy elements come from neutron star mergers. I should look into that. They are much rarer than supernovas, so that implies that they are much more efficient at either making or dispersing the elements they make. Unfortunately, pop sci videos and articles just present things as hard facts, whether or not they are very uncertain. Then later they sometimes tell you the opposite thing and you don't know why.
The "great filter" hypothesis being only kinda a general idea in the first place, I wouldn't assume there's only one. It's true that in physical systems, usually one effect dominates, but let's not assume that nuclear war isn't a problem yet.
