If interested in this kind of thing, I always recommend Issac Arthur. He describes the Fermi Paradox and related concepts 100x better than anyone else. Some relevant ones: The Fermi Paradox Compendium https://www.youtube.com/watch?v=rDPj5zI66LA https://www.youtube.com/watch?v=rDPj5zI66LA Fermi Paradox: The Dyson Dilemma v2.0 https://www.youtube.com/watch?v=QfuK8la0y6s https://www.youtube.com/watch?v=QfuK8la0y6s I believe he would say that there is no really good explanation to why we don't see other intelligent civilizations except that we are effectively the first (at least in our galaxy), and intelligent space-faring life is exceedingly rare. This is a similar conclusion to Robin Hanson here, but I think I think Issac Arthur does a better job of deeply explaining it. I think both would agree though.
