What I’m about to say I am serious as this was told by my dad who as a kid actually walked behind a horse to plow a field and was very familiar with such tools and their history.
Many horse drawn plows had the moldboard part of made of wood. When the technology moved to all steel plows there was the believe that the steel would sour the soil and ruin the crops. As we know, this fear was unfounded.
Point to be made is those that do not understand new technology tend to fear it.
I personally do not understand 5G, but I will not fear it until visible evidence is out there to prove it.
Madam Curie took a similar stance. She died of radiation poisoning, or was it cancer?
So I looked it up: Marie Curie died as a result of leukemia caused by the action of radiation. She was known to carry test tubes of radium around in the pocket of her lab coat.
From my navy nuclear power days, I remember radium as an internal hazard. She, like the paint brush crews that painted the dials on watches, probably ingested a great deal of radium as she likely didn't follow Fauci's advice to frequently wash your hands.
