There's a specific writing style for globalized English that AI's use. And then this post also had none of the stylistic flourishes that a real author might add. And then simple things like constructing a table of 68 libraries or whatever organized by relatively subjective categories. That is something that nobody is going to do by hand.

Perhaps the apparent hallucination they mentioned in their comment?

Haven't you heard? It's cool to dislike things "because AI".

Notice that the commenter does not take any specific issue with any of the content but just writes the entire thing off as possibly untrustable "because AI".
