I am not sure will all culture remain immune to the "curse" of modern comfortable lives that lead to low birthrates. This remains unproven.
And based on current trend it seems that it's the most religious group ( Islamists, Orthodox Jews) who props up the birthrates. But they are also economically most unproductive and most anti-science ones, so I really unsure where this will lead us.
