"The Fatal Flaws of Generation Ships in Sci-Fi"

Generation ships in science fiction face numerous challenges that can lead to their failure. These challenges include civil disorder, cultural amnesia, inbreeding, lightspeed leapfrog, and mission drift. Stories of mutinies, civil wars, and conflicts over limited resources are common in generation ship narratives. Additionally, the isolation and passage of time can result in communities forgetting their history and purpose. Inbreeding due to small gene pools can hinder the survival of passengers upon reaching their destination. Furthermore, advancements in propulsion technology may render the long journeys of generation ships obsolete. Lastly, the cultural transformation that occurs during interstellar travel can lead to divisions and differing goals among the ship's inhabitants.
