This angle is touched on in the article, as the words on a page script vs Robin's performance of it which is drawing from his unique human experience which would have been different from another actor (the lived experience throughline the article is making, not necessarily the experiences being described in the script, mind).

I do think though that article is a bit nebulous in parts, in the sense that articles and books we read are also just words on a page and its those mediums LLMs are similarly using, which is why I think they attempted to morph into a point later in the article about the acted performance.

I still get the gist the author is trying to convey though, in that through lived experiences we crystalize and hone in on the things that matter which allows us to have actual first-hand opinions rather than just second-hand ones from others. It's those first-hand experiences that are often most valuable to others and drowning them out in an avalanche of either stylistic or wholly generated slop makes them more difficult to find.
