Some examples in the book include the Wendat people and Teotihuacan. You can also check out the book’s wiki page https://en.wikipedia.org/wiki/The_Dawn_of_Everything.

One of the core conclusions of the book that you may find interesting (quote from the wiki):

Based on their accumulated discussions, the authors conclude by proposing a reframing of the central questions of human history. Instead of the origins of inequality, they suggest that our central dilemma is the question of how modern societies have lost the qualities of flexibility and political creativity that were once more common.

I recommend reading The Dawn of Everything by David Graeber for more details on societal structures of the past

from what i understand, the real world hybrid data is significantly worse than its WLTP test data. so much worse that it’s only a 25% improvement over petrol/diesel instead of the 75% improvement that would be expected given the WLTP.

Not quite what you’re asking for, but during WW2 the US employed Navajo speakers to use their language for certain verbal communications because it was so different from popular languages and hard to decipher. There’s a lot written about them out there. I would also recommend checking out The Code Book by Simon Singh, it’s a great recap of the history of secret codes and breaking them.

they may be able to read certain data from another instance but their current platform allows complete surveillance of what you looked at, how long, every click and scroll, etc while also being able to feed that in to manipulating what you see.

imo it will be basically impossible to have that kind of impact on people from instances not controlled by them, particularly if the other instance defederates so they don’t see meta instance content.
