From a technical standpoint, this is incredible. A few years ago, computers had problems creating grammatically correct sentences. Producing a consistent narrative like this was science fiction.
From an artistic standpoint, the result is... I'd say: incredibly mediocre, with some glaring errors in between. This does not mean that an average person could produce a similar chapter. Gemini can clearly produce better prose than the vast majority of people. However, the vast majority of people does not publish books. Gemini would have to be on par with the best professional writers, and it clearly isn't. Why would you read this when there is no shortage of great books out there? It's the same with music, movies, paintings, etc. There is more great art than you could ever consume in your lifetime. All LLMs/GenAI do in art is pollute everything with their incredible mediocrity. For art (and artists), these are sad times.
It's more nuanced than that. There are certain material/content where it is mandatory/necessary to read them.
Ideally I'd prefer to read material written by a the top 1%ile expert in that field, but due to constraints you almost always get to read material written by a midwit, intern, junior associate. In which case AI written content is much better especially as I can interrogate the material and match the top 1%ile quality.
Quality is its own property separate from its creator. If a machine writing something bothers you irrespective of quality then don't read it. You think i would care ? I would not.
If this ever gets good enough to write your next bestseller or award winner, i might not even share it and if i did, i wouldn't care if some stranger read it or not because it was created entirely for my pleasure.
