Though I enjoy post-apocalyptic movies and books. I always felt that they underestimate the proven potential of humans. It is great to watch things like Mad Max, where people drive stacked cars and wear armor made from scrap metal and cooking ware. But just look what they could do 1000 years ago what is possible without modern needs. Given the environment in those scenarios is much harsher. But we would have a head start in knowledge and tools. I believe, in no time, craftsmanship like this would return. (not that it isn't still around). Beautiful!
