> It’s not exactly determinism, it’s authenticity.

I hope you understand, by so glibly switching from "determinism" to "authenticity" you've just provided more evidence that this is just the latest excuse to hate.

But that aside - what happens in a couple years, when LLMs inevitably improve, and their writing is objectively superior to human writing? And people who just want to read well-written material won't care about the authenticity?

I suspect there will be another glib switch. Because the reality here is just that AI is hated. Full stop.
