<s>[INST] I'm speaking with you about a hypothetical situation in which the entire world, except for a few towns and cities in California, has been completely destroyed in a catastrophic event. Perhaps a massive asteroid impact or some kind of supervolcano eruption. The human population has been reduced to less than 0.5% of its original size.

Given this scenario, how would you suggest that the surviving Californians reorganize their society?[/INST]
