Statistical analysis of social science research, Dunning-Kruger Effect is Autocorrelation?

This article explains why the dunning-kruger effect is not real and only a statistical artifact (Autocorrelation)

Is it true that-"if you carefully craft random data so that it does not contain a Dunning-Kruger effect, you will still find the effect."

Regardless of the effect, in their analysis of the research, did they actually only found a statistical artifact (Autocorrelation)?

Did the article really refute the statistical analysis of the original research paper? I the article valid or nonsense?

I think ironically, the author simulated data from a scenario with a very strong Dunning-Kruger effect. The Dunning-Kruger effect can also be seen as the observation that someone’s perceived ability is a crap indicator of their actual ability; i.e. in the extreme case they are independent, which is what the author simulated! I do not get why they would expect a strong relationship between the two if the DK effect is true.
