How can AI chatbots like ChatGPT be used responsibly in healthcare, customer service, or other industries?

And how exactly? That is the objective, but that is just like saying "Wikipedia will provide more accurate articles in the future". The question is, I am fairly sure, "how", not "what".

I understand that I may or may not be harsh in the tone used here, but yes, I want elaboration. "I don't need sleep, I need answers", said the great Sheldon Lee Cooper sometime before now and the not-so-great me myself right now.
