I can quote from I Ching [Book of Changes] regarding change as the invariant element. This change was ideologically driven by an elite subset of society. Certainly not an organic development, in my opinion.

[p.s. Did we read the same Frank Herbert? My Frank Herbert highlighted the fact that "the ways" in Arakis were influenced by an occult group called the Bene Gesserit ..]

[p.s.s.: https://dune.fandom.com/wiki/Missionaria_Protectiva -- point being societal 'change' is almost always subject to organized control, internal or external.]
