The Portiids resolve the conflict by using the nanovirus to re-engineer humans to be more empathetic. This reflects the author’s liberal politics that key parts of human (individual and social) psychology are pre-determined by physical substrate rather than social relations. “Human nature,” whether “material” or metaphysical. We already have a way to expand human empathy without conceding to the arguments of 19th century liberal scientists — it’s called communism.
All of this happens because the author wills it according to his personal, eugenicist, politics. I’m not questioning in-universe strategy. I am questioning the politics of this subgenre of science fiction.
