There are plenty of signs if you look for them.

- "But the same closure that empties a granary fills somebody’s brokerage account." Claude is obsessed with comparisons linked by "the same". There are several instances, like "Poland made the same swap, with oil" (but that one is odd because "the same" isn't referring to anything).

- "Europe’s potato belt tells the story in a single season": Claude also loves this "noun verbs the noun in a single noun" phrasing.

- "A country that loses its regular supplier does not only pay more. It ends up dealing with people it does not know." Claude's classic "it's not X, it's Y" constructions.

- "Strategists do not describe a stampede home. They describe Japan quietly ceasing to be the buyer everyone could count on, and long-term borrowing costs rising everywhere as a result." A variant following the pattern "it's not X, it's Y, and Z as a result." This is an interesting pattern, one that I don't think I've ever seen a human write. A human would likely write "...leading to rising long-term borrowing costs" or similar.

- The use of a verb (rising) there in the third part is typical Claude, as it really likes to verb when a noun would read better. Other examples: "markets price another rise"; "volume freezes, prices stay put and sellers wait"; "after five years the rate floats".

- "The test Tusk describes is a test of belief, and it arrives just as the Pentagon decides how many Americans stay." The juxtaposition here (a test that arrives) is very odd and typical of Claude.

- What's also generally striking is the proliferation of "X becomes Y" phrasings, which is something Claude loves to do. Price shock turned into empty pumps. A story is told in a single season.

I'll stop there.

What's fascinating to me is that I personally find this kind of text exhausting to read, but apparently other people don't notice it at all.

If we ignore the AI stuff, I will still say this is not good writing. What's so grating and noticeable for me is the monotonous style. The short, clipped sentences like little stabs of information. It never varies; the tempo is just fact, fact, fact. It's absolutely exhausting to read pages and pages of this.

Good non-fiction writing is enjoyable to read for a myriad reasons; authors use metaphor, juxtaposition, tempo, humor, irony, allusion, and all sorts of techniques to make an article enjoyable to read. Just throwing down facts one after another with this kind of breathless, staccato noir voice is not that, in my personal opinion.

I don't know how much AI is to blame, maybe the Polish version is different or if this is a deliberate style.
