I like to disagree here. Despite the downvotes, not many people write or talk like that. It is not that common, at least in english. Contrastive framing is a pretty low-effort, high-attention signal, which makes sense in e.g. summaries, titles or ads. AI uses this as training data, and once you have this data, reinforcment learning will only deepen the usage, e.g. it will appear more often. Because it "sounds" familiar.

I'm sorry, but I do not buy the "people talk like that" argument. It's anecdotal evidence for me, sure, but I'm waiting for facts.
