Your other question - is the human race becoming lazy and too reliant on technology? - that's a great question, with no easy answers. A glib response would be: "That's what people said about any major technology advance in the past - e.g. robotics in industry; computers; mechanised farm equipment; steam engines." But they were right then, too. As we move further from subsistence living, we become more dependent on the interconnecting technologies that sustain life (and provide so much more than just sustenance). This interconnecting "grid" is both fragile (so many break points) and robust (so many redundant connections). As complexity (and redundancy) grows, to me it appears that the likelihood of a disaster decreases; but the impact of a "successful" disaster increases. I guess, over time, it makes sense to plan for some air-gapped alternatives to be built in parallel.
