Aside from journalism, which takes a few factoids and generates a plausible narrative, another main application would be psychotherapy/counseling. You don't have to be accurate or even all that grounded in reality when dealing with people's emotions, moods, and self-perceptions.

Apps like Woebot and Wysa claim to have had "millions" of sessions with people, but there are not many reviews of them on reputable therapy sites or in therapy publications. It's hard to assess whether they are useful at all. My own brief and limited experiments have produced more frustration than anything else. Maybe that's just my inexperience with chatbots, but adoption is going to be slow if it requires a lot of learning.
