Any true human-level (or even rat-level for that matter) AGI would need to have actual innate traits such as curiosity to drive lifelong exploration and learning. That seems a pretty minimal bar to meet to claim that something is AGI.
I suppose in context of an article about giving Claude a character (having it play a character) then we need to interpret "having a trait" as "playing a character having a trait", because it certainly is very different from actually having it.
