It's a construct that long predates AI. And using it with such intensity and frequency is more likely a sign that this _wasn't_ AI generated, since AI writing tends to _not_ repeat things quite so often.

I doubt a human would use it repetitively, even if it is common. This was most likely written paragraph-by-paragraph by AI, causing the repetition, if I had to guess.

I can't wait for the EU AI Act to require mandatory labelling for AI-generated content.
