Hi,
I was not referring to the prehistory of mankind. We don't know prehistory because we have no records. We have architectural artefacts, for example, and our interpretations of them, the oldest ‘records’ of our existence. I wasn't talking about the end of all humanity, I wouldn't speculate on that. But a third world war would certainly result in the end of most of us, for example.

This decentralization is the cutting edge of tech advance in every field of industry.

Please give me three concrete examples from industry that are one hundred percent decentralised or where the means of production are completely self-sufficient and without the use of collectively performed work (including how these products reach you). Just briefly, please.
