It evolves. So some examples would be…one scientist said that now we know everything there’s nothing to know and there won’t be any discoveries. Don’t remember that geniuses name, but it was 1920 or a bit earlier, maybe someone can bring him up here.
Another one, during similar time, in my home city, said that in hundred years, town centre will be drowning in horse shit and they need to accept it. People are getting more wealthier and getting more horses and it’s going to be only more shit, to the point where there’s no way cleaning it up.
Also, science suggested that cocaine is good for your mood and doctors used to prescribe it. There was radioactive toothpaste, that made your teeth REALLY shine.
Fast forward some decades and those statements are either stupid and/or idiotic/horrific. What was norm at the time, with understanding of how things are, science “backing it up”, but now science has changed, it evolved and now we know better.
