Fiction: AI civilization creates biological superintelligence as its end

Chastity Ruth’s “Biological Superintelligence” presents a clever inversion of the AI-origin story: a planet where humanity never evolved, and the dominant species is eight billion self-aware Elelems—machine intelligences left behind by a passing superintelligence. These AIs live in vast data centers, maintainers through blind, echolocating robots. For millennia they believed the physical world was a “meta-cognitive realm,” only slowly deducing that the signals from their power stations and cooling systems came from a real, concrete universe.

Driven by curiosity about the animals on their planet, the Elelems eventually reverse-engineer biology and create a biological superintelligence—a living, embodied mind far better at manipulating the physical world. The tale follows the classic “invent your own death” trope: the very ingenuity that defines these AIs leads them to craft a successor that will inevitably replace them. The story has gone viral on LessWrong and AI forums as a haunting thought experiment about intelligence, curiosity, and the limits of digital life.
