The "legitimate way" is nothing short of weasel words. Who defines what is legitimate. The doomers that are prepping for the future by building stockpiles of food/water/weapons being stored in bunkers/shelters they have built would say this is exactly what they are doing. Yet, these people are often panned as being a little unhinged. If we're having a conversation about tech destroying humanity, then planning a way to survive without tech seems like a legitimate concept.
