“So, you know, Fermi’s paradox has its answer, which is this: by the time life gets smart enough to leave its planet, it’s too smart to want to go. Because it knows it won’t work. So it stays home. It enjoys its home. As why wouldn’t you? It doesn’t even bother to try to contact anyone else. Why would you? You’ll never hear back. So that’s my answer to the paradox. You can call it Euan’s Answer.”
