As a species, humanity is about 50,000 years old. Millions, if you include our most obvious ancestral species.
The claim that neologism-of-choice is a "new" system is extremely unlikely to be true. What is more likely is that the new system is a reinvention of a system that has been seen hundreds of times under hundreds of names. Social structures tend to be evolutionarily convergent, depending on prevailing constraints. If a given structure is rare, that is because it relies or can only exist in a peculiar environment (eg Valve + massive profitability).
Truly. There is nothing new under the sun. Including totally "new" social systems that "work" because of short-term enthusiasm.
