or it might be changing from anecdotal human to technical research human. Here's my question - if you had read that 5 years ago would you think it was written by a human who had done some reading on the matter, or would you think they googled it and copied some of what they found.

Obviously 5 years ago we couldn't have worried it was an LLM, but if you wouldn't have thought someone just copy pasted something without understanding it, or someone was crazy on drugs when they wrote something, then it seems somewhat unfair to give people this new accusation.
