>Mass privacy invasion is probably one of today's trends that our descendants will look back on and say "what were they thinking?"

I'm not sure about that. The slope is not going to change direction, so it's only going to get worse. The newer generations will look back and go "what was the problem the old timers were complaining about, besides getting off their lawn?" I have a kid that just missed out being part of the millennial group. She already thinks I'm a curmudgeon about things. By the time she has a kid, privacy will just be a word to learn the definition to understand what people were talking about as it's simply not going to be a concept they care about. Maybe one more gen later.
