A lot of truth there.
You know there are the extreme wealthy in lofty places, who'd love to eliminate most of the worlds population.
They no doubt they see most people in modern day planet earth as a burden, who use way too many resources, are difficult to control and are a direct threat to those living in those lofty places.
They would love to see the carbon footprint dramatically reduced. And since they've looted most things like Social Security etc, it would be much easier to deal with when just a few unwashed peons take to the streets.
For all the gun control rhetoric going around these days, these make guns completely obsolete. In pretty much all ways. No more anonymously picking off old steve up the road (with a gun) because you just plain don’t like him. That would involve going somewhere near old steve and plugging him yourself. You could just program his facial recognition information into a ‘hit man’ drone and wait.
He will have few defenses against this attack.
Likewise, if the elites want to take you out with this tech, your own guns will be useless. Do you plan to shoot every bird or mosquito cloud on your property?
