Agreed. I think LLMs have actually made good writing stand out more. Now everyone who wasn't a great writer is just producing Claude-isms which are easy to detect. If it doesn't smell like Claude, it's probably good.
But it's not practical or always possible to avoid reading AI-writing, so to counter that, I've been binge-reading Anthony Trollope novels. Great writing, good entertainment, and deep psychological insights, better than any British novelist, imo, in any era.
