Yeah, there is no "simple solution".

One thing is that GPT-5 famously (initially at least) reduced its "chitty-chatty" nature and gave more direct cut and dry replies......users rebelled and twitter was filled with howls of "they've killed the soul of GPT!".

However, (a) I think it was a good thing, and (b) I think it probably came from health & safety people within OpenAI who realized that they must de-personalize a bit to limit damage to people who have a tenuous grip on reality.

It may well be in 50 years we look back at: "friendly cutesy AI interactions" as generally dangerous and not a best practice.
