I don't think decentralization has anything to do with privacy.
But you're right, this probably is the end of human history. Almost anything is possible with technology advancing exponentially from this already-advanced point. We approach the information singularity, long before which everything about our lives will have to completely change, likely into a permanent state of flux to be able to accommodate the pace of technological advance.
Which means there probably will never be "future genealogists", unless we're talking about the very near future.
you are prob right that decentralization does not equal privacy although I used to truly believe it did...now I understand why civilizations disappear without a trace -
That's a disturbing thought, friend.
I guess... but we are investing everything onto "online" - sadly - although this would be a perfect time to just get off the internet and live in REALITY.
We could start a new Amish-like project, but instead of living in 1799 forever, we live in 1999 forever! No smart phones :D
I would LOVE that
Getting it started is another matter. I don't know who is up for organizing that kind of thing. Maybe several small communities, to keep things small. We need somewhere to go, too. Maybe a national park will have to be seized for the people's use? Heh.
I tried to do this once - I have property in Southern Colorado - but it didn't work out - didn't get enough people at one time together https://all-are-welcome.weebly.com/ plus my property is not the greatest - just cheap...and there is an aquafir and a thermal aquafir...but it's hard there and the economy sucks and there are no trees... there is a place out there like that - https://earthart.org/pages/hom and there are many more communities elsewhere that hare already going that one can join... https://www.ic.org/directory/
