I found the "Critiques of elitism" section and noticed this sentence:
"Reviews of Mao II (1991), for instance, highlighted the novel's focus on a performance artist protagonist as emblematic of this tendency, with detractors accusing DeLillo of prioritizing esoteric concerns over relatable human experiences, thereby catering to an academic or literary insider audience."
But Mao II does not have a performance artist as the protagonist, that is the book The Body Artist. Which seems like an obvious failure of the AI model to properly extract the information from the sourced article.
Also strange is that the sourced article (from Metro times) just as a passing comment says: "DeLillo’s choice of a performance artist as his protagonist is one reason why some critics have accused him of elitism." - so it would seem that it is being used as a primary source though it is actually a secondary source (which itself doesn't provide a source)
Overall I'm not too impressed and found some pretty predictable failures almost immediately...
