Ted Chiang is an author who usually leaves me speechless, and in doing justice to the title of this short story, I was in great silence when I finished reading it. I had to process the whole of the story as I had to when I read his outstanding Stories of your life.
A kind of parrot who lives close to the Arecibo Telescope in Puerto Rico reflects on the proximity of his species' extinction. This is the venue that the author uses to talk about Fermi Paradox, but also how we, humans, are leading the way to the extinction of a whole great bunch of species of animals and plants, not to mention our extinction.
Even though I adore astronomy/cosmology issues, it is of great importance that we question why we look so much to the stars in search of alien life, while we have such a huge variety of species on Earth that we are so deaf to and we decimate without a second thought.
By sticking to this that we call "reason", we have entitled ourselves as the ones to own everything under the Sun that we can grab our hands at; as the only ones that can express all of the the other species' willingness; as the ones who can decide, even among us, humans, who deserve to live and who deserve not. Let alone that proof of intelligence to humans in what concerns non-human animals is the ability to communicate to us in human language (the stupidest thing ever; we are not the center of the whole universe).
This may be the reason why I so much fear the moment humans start having colonies on Mars and other planetary bodies. It will be a reason to destroy these new habitats and to keep on destroying Earth.
Humans, in some ways, should be called monsters.
