Here is a spark for you. I heard the large particle collider is evil. Did you hear about the guy that came from the future to destroy it? I think it was a joke, but you never know.
There is the aspect of black smith shops and the work they need to go through for the fuel for the forge, that alone is a huge task. I for sure would not want to go back to the stone age for tools. I am happy with the level of technology I have settled into.
I am coming out, I hide metal in my frames! I feel better now.
