Ya, I guess I can see some uses for it, but nothing that makes the risks of it’s existence worth it.
It seems like every tool/tech will be used by good people to do good things and bad people to do bad things. Some things like a spoon are handy for getting good things done but not very useful to bad people to do bad things with. Other tools like mood recognition might be quite handy for bad people looking to control others, but only moderately useful to good people.
Tools in that second group I think we should be wary of letting them exist. Just because something can be done doesn’t mean it should be done or that it can be called “progress”.
