>which ones successfully isolated and hid from (real or hypothetical) bigger badder ones?
South Sentinel Island, famously. Still existing in the stable equilibrium established a millenia ago. Oh but they don't have iphones. Big whoop. If our modern supply chain falls apart due to climate change, not an unrealistic bet, we are finished and will probably kill ourselves and you and I will die in the violence to come. They will not even notice anything, and will exist as they have existed for millenia more. Their civilization and state of technological development is actually far more robust than ours.
