The Sci-Fi naming problem: Are #LLMs less creative than we think?

The most well known LLMs seem to always give the same names to the protagonists of #scifi stories.

Why do they do that? Are they not creative?

Who are Dr Thorne and Anya?

In my AI agent generating sci-fi stories (developed with #langchain4j, deployed on #CloudRun) I was always encountering the same names again and again:
