> It feels like such a worthy cause to make sure they stay "uncontacted": they obviously used that fact to do great deeds. Indeed they keep the tradition of carrying a great deed long lost for most humanity. The deed of still being able to thrive using just stone-age tech. I suspect that in case of sudden collapse that ends civilization, these groups will be among the few ones able to repopulate Earth, because the overwhelming majority of "civilized" people will die in a short time without all the technology they are used to. The continued existence of human groups living in stone age is an existential insurance policy for us.
