My first thought as well. I personally don't find these types of "studies" very interesting, but I assume I'm not the target audience. For someone not well exposed to AI, it might be interesting.

Especially for someone not "well exposed" to generated text, they might think the words carry meaning the way they do when someone thought about the question and came to an answer. If anyone can interpret this, it's the people who know what they're dealing with (be it from exposure or, better, from a conceptual understanding)
