“I’m pretty sure that if no physicist had ever existed, I would still be here.
In fact... I am here despite those physicist who have created weapons of such mass destruction that they will likely eliminate the majority of life on earth if they are ever used. They haven’t been used... Yet!
Wait for it.”
How old are you? You sound like the radicals of the 60’s.
There is nothing radical about it... I’m fully aware that nuclear weapons have prevented war since 1945... But I’m also fully aware and not too foolish to think that some bonehead who may not even be born yet, will eventually use those weapons.
You can’t dis-invent the wheel... They’re round everywhere and used everywhere and somebody will eventually use those weapons. Hopefully not in my lifetime, but in somebodies and after they are we are done as a species... We won’t be travelling to any star system anytime ever.
