I'm not trying to be recalcitrant, rather I am genuinly curious. The reason I ask is that no one talks like a LLM, but LLMs do talk like someone. LLMs learned to mimic human speech patterns, and some unlucky soul(s) out there have had their voice stolen. Earlier versions of LLMs of LLMs that more closely followed the pattern and structure of a wikipedia entry were mimicking a style that that was based of someone elses style and given some wiki users had prolific levels of contributions, much of their naturally generated text would register as highly likely to be "AI" via those bullshit ai detector tools.
So, given what we know of LLMs (transformers at least) at this stage it seems more likely to me that current speech patterns again are mimicry of someones style rather than an organically grown/developed thing that is personal to the LLM.
Not saying the article is bad, it seems pretty good. Just that there are indications
Might as well say "You can tell by the way it is".
You're staking personal reputation in the output of something you can expect to be wrong. When someone gets a suspicious email, they follow your advice, and ChatGPT incorrectly assures them that it's fine, then the scammed person would be correct in thinking you're a person with bad advice.
And if you don't believe my arguments, maybe just ask ChatGPT to generate a persuasive argument against using ChatGPT to identify scam emails.
