Not to diminish the work of psychologists and therapists, but I do suspect that there’s a range of mental health problems that can be ”treated” at least in part by the use of chat bots like this. Something that can ask useful questions, provide appropriate responses, and engage in a conversation would be valuable in cases where “talking it out” is a big part of the treatment. People might even be willing to be more open to saying things to a computer that they wouldn’t tell a person.
