A vaguely plausible way for some humans to survive, taken from funposts on regular /co/ (mostly from these threads: https://desuarchive.org/co/thread/145249737/#q145249737 https://desuarchive.org/co/thread/145265199/#q145265199)
>On the far fringe of known space lies a lush garden world >For centuries it served as a nature preserve and a tourist spot with few permanent inhabitants >Until The Absolute Solver came >First Earth fell, and the colony worlds followed >As soon as it was understood that The Solver manifests through digital technology, a radical but obvious solution appeared >A desperate group of colonists fled to the garden world, then destroyed their ships and all of their advanced technology >Generations passed and the colonists adopted a hunter-gatherer lifestyle >Elders spoke of their ancestor's greed destroying the world of Urrath, where men killed each other for shiny rocks >It was said that by cultivating indus trees, the ancients brought forth a horrible beast that consumed everything >Now, near the end of the 31st century, the last man who ever lived to see those days has died >The younger grugs wonder if any of those stories were really true >Only the shamans are allowed to even see the mark of the beast, and no one has ever seen the so called "flying demons" that ate the men of Urrath >Until now
>Despite destroying whatever they could find, some derelict spacecraft and stations littered their system >The few cities built on the garden world were bombed to hell and back but there may still be some tech lingering underground >J was fixing up the lander to go there during the credits
