The Wikipedia article (https://en.wikipedia.org/wiki/Dark_Ages_(historiography)) is a one-sided presentation that begins with denying the historical reality of a period called "the dark ages", continues with a history of the term itself, and concludes with a brief section on non-academic use of the term and reiterates the claim that the periodization is a "myth of popular culture". The article barely mentions the events of the period.
If you read the Grokipedia article on the same subject (https://grokipedia.com/page/Dark_Ages_(historiography)), you'll find not only meta-discussion of the origins of the term, but also in-depth exploration of the events of the period, the causes of the decline in living standards, and arguments from prominent scholars on both sides of the debate about the utility of labeling this period a "dark age".
The Wikipedia article doesn't mention Ward-Perkins, a prominent scholar in the camp arguing that the dark ages represented real material decline. The Grokipedia article cites him extensively.
The difference is interesting because Grokipedia's presentation is much closer to the truth. The dark ages really were in fact dark. In some parts of Europe, literacy itself was almost lost. Trade did collapse. Living standards did fall. We have tons of archaeological and literary evidence attesting to this decline. Tabooing the term "dark ages" does nothing to deepen our understanding.
Yet the Wikipedia article is one-sided because, frankly, its editors see themselves as enforcers of academic orthodoxy.
There are thousands of disputed subjects like this outside the culture war everyone gets worked up about. It really is the case that Wikipedia presents one side of live academic conflicts and gatekeeps sources to minimize heterodox perspectives -- again, all having nothing to do with mechahitler or the culture war or whatever.
I'm glad there's more epistemic competition in the world now.
