It's all downside. I've seen cases where this is used to 'give murder victims a voice' recently, both on CNN where they 'interview' an AI representation of the victim and in court, where one was used for a victim impact statement as part of the sentencing. Those people would laugh you out of the room if you suggested providing testimony via spirit medium, but as soon as it comes out of a complicated machine their brains sieze up and they uncritically accept it.
