At any moment I might disappear, my life will end, we don’t know how soon. The Taushiro don’t think about death. We just move on.
But the Taushiro won't be able to "move on." In Amadeo, they have come to the end. Casey's account of his conversations with Amadeo is deeply dyed with an almost unbearable poignancy, with the distress of an irremediable loss, of a sorrow beyond any power accurately to name it.
As I read Casey's story, I could not help but universalize. This story made me think of the history we are making now, as we drive the human species ever closer to extinction.
Perhaps, if we can feel what it would be like to be Amadeo (because we are so much like Amadeo), we can save ourselves from the extinction event that even now, we know, is coming after us, as the invaders came for the Taushiro.
