Many previous chatbots including the ones that talk to people through their phones and most of the ones in science fiction, were always very sarcastic
That is, they were either like sarcastic teenagers Or worse like green bodied submissive alien women personalities.
ChatGPT writes like a friendly aunt or uncle – or perhaps the way a nice teacher responds – and it chastises gently about some unprofessional subjects that could get it in trouble
I find it to be a warm and professional tone. Aloof but can be warm when the little human shows signs of intelligence.
