I’d expect a few people to be still alive after 2000 years from both groups, but how many I have no idea.
Given that they’d know modern technology and potentially reproductive cloning was possible, there’s an obvious common goal for a significant proportion of them, more so for women than men as it’s so obviously a lot more likely that they’d be able to manage it.
Both groups would probably decide to work towards this after it became obvious that they really weren’t aging, and they really couldn’t leave. For the reason of difficulty, I’d expect a larger consensus among the women than the men: I’d expect more of the men to argue for exploration to try find some women, though this might be a major goal for the main female group as well, I’d guess it’d be lower down the list (even if you know it’s not possible for them to get back to earth they can’t know). They’re supposed to be above-average intelligence after all, so most of them will probably realise that they’d be better off working together, and might be able to achieve something none of them can do alone.
Given a common goal for a large group, a settlement with agreed rules would pretty much follow, presumably with a scientific group supported by the others- food should really not be a problem, as with even a basic level of agriculture in these conditions, I’d estimate that 20-30% of the population could specialise in farming and sucessfully feed the rest, with a static/slowly declining healthy population. Other groups would probably start specialising in building, and making clothes or other necessities, some would be involved in disputes, entertainment, paper making and library copying as well as generalised society running. Some people in both groups would refuse to go along with the collective and bugger off into the wilderness and might try form their own unlikely-to-last-mini-society, but it should still leave at least a few hundred, and probably a few thousand to dedicate themselves pretty well exclusively to scientific purposes.
We really can’t look at previous cultures for parallels, as it’s never been the case that the whole culture had an actual tangible goal to work towards, with written instructions for a large part of the way; neither has it ever been the case that they had no dependants to support (or very few- there will presumably wind up with a few injured/disabled group members needing care at some point). It may be a small culture, but that’s a pretty major list of advantages, especially considering that likely some of them would be starting off with reasonable skills.
Incidently, I don’t think the gender average strength difference would make any real difference- most of the jobs that will need strength are jobs that benefit several people (land clearance, building etc.) so they could be done by several people. I don’t think the food and housing problems would be a major issue, at least after the first year or two, and temporary shelters and foraging/hunting could keep almost all people alive, if not happy and healthy for that time. The start of some form of collective would probably happen in these first years, probably as a result or preventative measure of conflict over access to the library and tools, depending on individuals.
The next major societal problem for the women, assuming they can find all the resources they need to eventually start mekin babbehs, would probably when they start outlivin’ them babbehs (presumably still all girls, unless they somehow re-engineer Y chromosomes from of somewhere)- I’m guessing they won’t inherit the no aging thing after all. That would be pretty damn depressing, especially after potentially hundreds of years of research, and would probably start a bit of a suicide wave. Once the tech was there though, the kids should be able to keep on with it, so they should be able to keep it going a while. I can’t guess how long it would run then though for any more than I can guess how long our present society can keep going for. The ‘goal’ that would probably have been holding the group together would after all have been acheived. Maybe the original members who decide to carry on would be able to hold society together, maybe not.
I’m not sure why, but I don’t think the men, if they manage the cloning, would find that as hard to deal with- possibly because they’d be able to make kids of both genders, and would be able to recreate a society like the one they were born in. Plus they’d be creating potential partners (however weird that might feel given the age gap), not simply children.
BTW, I’m curious as to why Acid Lamp thinks women are more likely to die in accidents and squabbling in this situation, seeing as that’s exactly counter to the norm. Care to elaborate at all?
