The ironic thing of course is that to the extent a distinguishing feature between human and LLM writing can be well-defined, it can be optimized against by the next version of LLMs, assuming a financial incentive.

At this stage, it's clear to me that we are indeed headed towards the "Mission. Fucking. Accomplished." world - https://xkcd.com/810/

That’s a shame, I haven’t been keeping up on LLM web fiction quality level. I’m an avid web novel reader myself and do notice a ton more new fictions these days compared to before. There are even some works where other readers pointed out a drastic difference in quality of a longer running web novel (maybe a year or two plus) where new chapters are worse and just have a bit of that AI smell. But I suppose I also feel for writers busy with their lives and are writing on the side.

Personally, I don’t know what I feel about AI written novels, I suppose if the quality is truly great and I can’t tell, then fine. But if it means a flood of low quality novels that’s a bit sad.

But long time readers often smell something off beyond what feels like new or amateur writer quality scents. I wonder how long this radar will keep working as models and tools improve. But there must be something about high quality writing that’s difficult to capture in an LLM today, I wonder if it’s mostly a data quality thing or it’s an actual model limitation.
