If you used GPT-4 well enough, you would know, at this point OpenAI does not need to pay any human to engage in online conversation, aside from legal reasons if any.

I personally created some content-creating bots with GPT-4, and it succeeded to a level that I don't trust anything I see online anymore. It does a better job than me, which doesn't say much because I am an engineer not a content creator. But still, I could get same results as one with a script that I made GPT-4 write itself.

...Yes, I am losing sleep over GPT-4's performance. If you are not losing sleep over it yet, you haven't really given it a genuine try yet.
