Sorry, I must be missing something, what's the problem here? I don't see OP citing ChatGPT, just that they were explaining their own belief system to GPT-4 and it responded by "simplifying" OP's beliefs into "orchestrated objective reduction". This is exactly the type of usage I would expect from an LLM; OP didn't use it to inform their decision, but to further examine the belief from another perspective or broaden their questioning around it.

There is a damn army of people doing this and I have no idea what they think they're contributing.

My personal conspiracy theory is it's ground work to set conditions for disinformation campaigns: the "I used an LLM/I used ChatGPT" people are there to make you look less critically at the other comments by giving a small queue that since they don't include those terms they just be more genuine.
