I’ve wondered why no one seems to be seriously putting effort into a genealogical ship. I’d be okay with being the first generation; I can’t possibly be the only one.
I guess there’s a place to be conserned that eventually a society might emerge within the genealogical ship that might cause them to loose their allegiance to the rest of humanity and go their seperate way. We saw this when european colonists came to the new world, they didn’t stay loyal to their home governements because of the difficulty to communicate across the ocean and the difficulty the home government would experience projecting their authority. Communication would be just as difficult with a genealogical ship and they might leave us forever, like we’ll never see any benefits from the genealogical ship.
And when you think about it that would make the most sense, because even when the final decendants of the genealogical ship find a new home world they’ll never come back to earth, their will be no travel. That world would become a different world for people who might not even consider themselves as human.
Conclusion: there’s no way to space travel unless a person can travel between worlds and still have enough of their lifespans ahead of themselves to do stuff to contribute to the wider galactic human soceity. Unless you want to live in the cowboy bebop world where the government is too weak to do anything so they have to hire bounty hunters to suppress criminal organizations competing governments, and you don’t know who has your better intrest and who’s going to protect you from who, be my guest, fracture human soceity before we’re truly ready to go out into space. It sure worked out well 100 years ago.
