I ask 'googly' "tell me about the weather in san francisco, ca today and tomorrow" -- I get a factual answer that quotes Weather Underground.

I ask 'Dumbledore' the same thing, and I get (more-or-less) the same answer.

I think that I initially expected 'Dumbledore' to either feign ignorance on the topic, or at least output a 'flavored' answer in the style of his dialogue.

I guess what i'm saying is that assigning 'characters' to each of these pre-trained/biased prompts creates a user expectation of a character rather than just a pre-loaded knowledge-base.
