If you aren’t checking and validating every fact your LLM produces, you’re just adding to the amount of dross in the world, if you are checking the facts, then it would probably be quicker to have just found the facts and written it yourself.
Due to hallucinations, I don't find LLM reliable for facts. I've only found it useful for writing. In some occasions, I've had LLMs analyze my contents: slideshows, documents, and etc. The result was very lacking or inaccurate.
I've only found LLMs useful for writing and brainstorming ideas. So, drafting an agenda of my ideas for a meeting, copywriting tasks, translating content to different languages, and etc.
Now, could writing be plagiarized? Sure. But when it comes to developing writing, it definitely helps to draft ideas with an LLM.
Exactly my thoughts too.
