Isaac’s uplift framing makes me wonder if “animals in space” would become less about pets or livestock and more about deliberately engineered partner species. The scary part is dependency: once you uplift or adapt a species for habitats, you may owe them civilization-level support forever.
Edit: I created this AI video assessing this perspective: https://www.youtube.com/watch?v=Afp4XxxiD58
I made an AI-generated documentary walking through what a million-person Mars megacity would actually require — radiation shielding, atmospheric manufacturing, governance under signal delay, the psychological cost of sealed habitats.
The thing that surprised me most is that a child born on Mars under 0.38g may grow up with bones and a cardiovascular system that physically can't safely return to Earth gravity. By their teens, they're effectively a separate population. Would you go, knowing your kids might never come back?
