For example, there was genuine fear in this country when airplanes were invented. Many people were horrified at the prospect of having these infernal "flying machines" up in the air. They envisioned that these machines would fall out of the sky and destroy their homes and property. Or drop bombs on them while they were sleeping. They saw airplanes overhead as a threat to their privacy. And so on and so on.
It didn't quite turn out like that and while the privacy concerns were certainly warranted (now satellites in space do the job more effectively), people don't even pay attention to all the planes in the air.
One of my favorite things to do just after sunset is see all the satellites moving through the skies. Many people are not even aware that you can see satellites with the naked eye just after sunset. They don't even think about them being up there. Even though these satellites are so sophisticated they can read the license plate off your car in the driveway.
“.... airplanes overhead as a threat to their privacy.... “ Now we have teens with friggin’ drones to invade a person’s privacy. LOL!
They'll have to wait for me to wash it.
