And actually based on my experience, customer sales agents, whether it's real estate or cars are notoriously dishonest. They may not hallucinate perhaps, but they leave facts unsaid, they will word things in such a way as to get you to buy something rather than get you to do the best decision - sometimes the decision could be not to buy anything from them.
So a ChatBot that can't intentionally lie or hide things could actually be an improvement in such cases.
