They appeared to have been ripped from a history book entitled 2000–2150 AD: The Emergence of Modernity. I'm repeating the text here verbatim, sans the header, which mentions only the title of the book. (Or perhaps it's the title of a chapter.)

Make of this what you will.

In the late 20th century it began dawning on the heirs of Western civilization that the archaic forms of rulership they lived under (and which they had held as the ultimate form of human organization) were actually enormous parasites. The first people to grasp this tended to be socially ostracized and were punished in a variety of ways, mostly informal. But they persevered and found comfort in the writings of like-minded men and women of the past, who had the good fortune to live beneath milder incarnations of parasitic hierarchy.

Soon books were being written on the subject and circulated among a small but devoted readership. Slowly, something of an intellectual movement began to form. The first great expansion came with the rise of the internet in the 1990s. The new ideas began spreading beyond small intellectual circles and into the minds of productive people worldwide.

The ideas advanced slowly. People of the era were, after all, forcibly schooled by those same parasitic regimes, and breaking away from a nearly universal system of thought was difficult, no matter how obvious the system's barbarity.

Still, humans have always been clever and self-referential creatures, as well as being gifted with effective memories. Little by little the new ideas, like so many seeds, began to grow. One person here spread the concepts to one or two elsewhere, who – a few years later when the seeds in them had matured a bit – spread them to still others. With a geometric certainty, the seeds began filling mankind.

But while this appears as an inevitable process from our perspective, it seemed desperately slow and uncertain to the people involved. Many of the earliest adopters died before they saw the fruit of their labors, which didn't appear in any significant concentrations until 2015 or so.
