If there were some evidence that the voices people hear are generated in a readable portion of the brain and you could train the AI on specifically those parts, it could be a powerful therapy. Hell, make it into a videogame RPG where the patient is the hero and the labyrinth they must conquer is their own mind. Their party could consist of good friends and trained psychologists who work together to probe, map, reveal, and conquer the demons in the patients mind through teamwork, collaboration, and shared experiences. However, it probably shouldn't be done outside of a clinical setting and there should be safeguards in place. The last thing I want is for some AI trained on my most psychotic thoughts to exist in any sort of reality, even virtual.
