The ironic part about these hallucinations is that a research paper includes a literature review because the goal of the research is to be in dialogue with prior work, to show a gap in the existing literature, and to further the knowledge that this prior work has built.
By using an LLM to fabricate citations, authors are moving away from this noble pursuit of knowledge built on the "shoulders of giants" and show that behind the curtain output volume is what really matters in modern US research communities.
I guess that makes this "standing on the shoulders of fabrications"
