I mean yeah a lot of ideas can be used to cause a lot of needless and avoidable suffering instead of preventing it which is what I think the actual thing is we want to avoid. Like in Gattaca it wasn't the gene editing that was the issue it was the dehumanization of a group that was the issue, unless they were editing themselves to be less compassionate but that's not in the plot. Once again I think we can talk without the name calling, I'm not being mean or rude to you personally and I would appreciate you having the same decency but you're free to do what you want. I guess I could say where I'm from and then you could just deny it. As for parlor walls, just get a few AI agents with an avatar playing out a plot you can interact with and it's essentially the same thing. Use a projector I guess and you got your wall.
