There are just times that we stumble upon writer's block.

Personally I have had multiple instances of me knowing the idea I want to express, but utterly failing to articulate it in a way that's understood by most people.

And I unfortunately do not have a human assistant, so for a second opinion on how to articulate the idea better, I turn to an LLM. (Yes, I am using my own idea!) I write something, ask the LLM whether it understood what I said, and make adjustments based on that. In this case, the text is 100% written by me, and the LLM is no more different than a random passer-by giving me advices.

But there are also times when the idea is so complicated that I don't really have a good idea on how to untangle all of that. Ideas that live in your brain as a bunch of abstract concepts, if you can get it. If I were to untangle all of that myself - it's fairly good chance that I'll just leave it for "another day" (read: abandoned). I won't be investing any more thinking into it, LLM or not.

So LLM it is. I dump my ideas (as a bunch of incomprehensible human gibberish ;P) into it, make it make sense of the ideas, generate an ideas-untangled paragraph, which I use as an inspiration (or basis, or template, or whichever word you think suits it) for writing my own text with my own voice and my own style. I was able to continue thinking because the LLM keeps my attention from drifting away!

(I always suspected I have some kinda ADHD, but shrug)

I understand where people are coming from when they reject all forms of LLM assistance in writing, it's just that I hope people don't turn it into a dogma of some sort.
