What you would become, in effect, is the fictional Soviet 'writer' from Sam Kriss' 2011 short story 'The Machine'.

I do not think there is anything to aspire to in that.
This caters to a different lets say need.
Like I said in another post it's more like low tech holodeck or maybe create your own adventure. Where the story evolves based on simple directives
As someone once said, "Fail again. Fail better."
And, anyway, so what if they are bad? They are authentically the product of a single human soul rather than some grey-gruel average of millions. There is an awful lot of value in that.
Maybe the tree system and branch switching would still work without attaching it to an LLM backend.
But the editor would have to be more advanced I think.
Would be cool to try and build something like that.
More broadly, you might be interested in language models because they are new, and you don't want to discount the value of new, constantly-evolving tools for your art form until you have explored them and understood their strengths and limitations.
I personally have not found language models very useful at all for serious work thus far. I am curious, though, about why many people are openly dismissive of the potential artistic value of what is an extremely new tool, and - maybe more importantly - those who choose to use it.
How other writers write doesn't strike me as any of my business, beyond what I can learn from their methods.
it can be addictive to tell stories with friends or world-build, so why not a 'friend'?
