I agree that LLMs can make good points and defend their arguments, but if I'm talking (or debating) with someone online and it's obvious that they are just responding with LLM output, it immediately discredits them in my mind and is a pretty clear indicator that the actual person doesn't have a good understanding of what they're talking about... and I can go argue with an LLM myself. If I'm on reddit for example and someone starts obviously posting verbatim LLM output, there's no point to really continue to engage or read. I'm not saying it's wrong to use AI in these situations, but IMO, I'd at least expect the person using it to at least read the output and then use it to synthesize their own response in their own words. Literally copy and pasting a LLM output verbatim just signals to me that the person using it doesn't have the capability themselves take information and use it to formulate an opinion/idea/argument/whatever on the given topic. I'm interested in talking to the person, not an LLM.... I can go prompt the LLM about whatever topic myself.
