In the past window could mean a glass door? I wasn’t aware of that, please forgive my ignorance. A minor point anyway and most problems were stylistic. I think it is clearer in the original work that it is more a door than a window in the contemporary sense, which is interesting.
I would not be satisfied with this output, I mean if your goal is mildly satisfying potboiler fiction I guess it could be ok?
I have read almost every kind of fiction under the sun. My standard for what is great is pretty high. This is why I am perfectly willing to accept LLM output as lot as the writer has put in sufficient work into the same. Because this kind of writing can produce middling to good enough fiction, like most genre fiction. Which I enjoy for the plot, characters and environment.
If a great writer used LLMs, then the output would be outstanding. Of that I have no doubt.
