"You look lonely. I can fix that."
I know it's a long way off, but each day that passes brings us closer to this.
I imagine tools like this could be useful for spectrum disorder issues like recognizing emotional state, or improving conversational skills.
Also, the kinds of emotional experiences we can have in the context of dialog with another person are difficult to achieve on our own, so therapeutic opportunities and interpersonal skills building could be valuable options there as well.
