Orwell was prescient (unfortunately). There's a lot of technology that can be used to invade privacy, and it can and does get misused. People fly drones over places they aren't supposed to be (like other people's backyards) and take pictures of people who thought they had a reasonable expectation of privacy. A few months ago, some idiots flew drones out to a wildfire in California and got in the way of the firefighters (which was not a privacy issue, but a safety one).
"Oh, you can’t help that," said the Cat: "we’re all mad here. I’m mad. You’re mad."
"How do you know I’m mad?" said Alice.
"You must be," said the Cat, "or you wouldn’t have come here.”
- Lewis Carroll, Alice in Wonderland
