Do the Amish have a collective divine life mission to act as a backup, a fail-safe in case of a long-term grid collapse? Have they single-handedly ensured that the “old ways” of self-sufficiency and self-reliance are preserved, and can be quickly taught to others if desperately needed? Were these times foreseen, and the Amish “volunteered” to play this role? What can Creator tell us?

Your question is describing things not far from the truth. In your thinking about the current state of the world and reflecting on the fragility of the modern conveniences you rely on, and also the vulnerability to have the underpinnings fail spectacularly to catapult you back to a primitive existence, you are seeing through this lens a deeper truth. The lifestyle of the Amish, widely regarded as highly peculiar and seemingly self‑denying and self-penalizing in studiously avoiding most modern conveniences, has a basic authenticity and sound foundation because it counts on what people can do with their own personal energy in most respects. And while that lacks the modern touch, the devices and gimmicks technology can entice people with, the Amish lifestyle has integrity, substance, and a reliable continuity of functioning consistently and well. People have well-defined roles that are concrete, measurable, and visible to all. So, from the perspective of an outsider, they might live quite primitively, having to farm their own food, tending livestock, learning carpentry to build their homes and barns, and many other implements needed for daily living, and so on, but the Amish are quite happy and, in fact, in many ways it is a superior lifestyle because it precludes the frivolous, the inconsequential, the indulgences that squander resources, time, and opportunity. The easier life gets, the easier it is to need amusements to substitute for tangible accomplishments as a reward and gratification. It is when people have time on their hands they can indulge in drinking and drug use as a lifestyle and still keep going. General affluence may keep them propped up enough to survive sponging off others or engaging in something unsavory but lucrative enough to get by. The Amish know something most people do not, that virtue is its own reward. Cutting corners may create the illusion of getting ahead, but ultimately there is a loss that must be reckoned with. Doing things the easy way does not build muscles, or character either. The gradual displacement of the early ways of living off the land, in a close-knit community close to nature, by an increasing technological intrusion sold to you, through manipulation, as representing signs of progress has been devastating in causing moral decline and decay almost to the point of no return. It is not too late to wake up and recognize what has been lost and seek a way to rebalance things.
