"Man had always assumed that he was more intelligent than dolphins because he had achieved so much — the wheel, New York, wars and so on — whilst all the dolphins had ever done was muck about in the water having a good time. But conversely, the dolphins had always believed that they were far more intelligent than man—for precisely the same reasons". — Douglas Adams

Makes a ton of sense, doesn't it. We're attributing our preferences - biological, cultural, etc. - to the good stuff, then later on "discover", piece by piece, that we're not that special. I know many truly intelligent people who do feel humans are special and it's been blowing my mind for decades
