'Like, "The series variously details the interplay between the mechanistic perspective..." What does this sentence actually mean?'
I'm not a big fan of this style either, which I think greatly tempts both author and reader to mistake style for substance, but it doesn't help that you've cut the sentence off mid-clause. "The series variously details the interplay between the mechanistic perspective and the catastrophic consequences it has in the real world." can be translated into something a bit more HN-ish as "The series discusses the interactions between machines and their catastrophic real-world consquences through a mechanistic lens."
While subjective, it is at least a sentence that contains real content, in the sense that it can be falsified, or at the very least, sensible arguments raised for and against it. I won't disagree that the style you are reacting against does tend to indicate content-free sentences, though.
