It's not extreme, it's what most people have had for millennia.
New technology is deanonymizing public space, invasions of privacy previously required great effort and expense, now they can be done trivially by accessing data on your phone, or now your car.
The ramifications of this haven't become clear to you because no-one important's decided to fuck your life over yet or you live as a conformist, but for many of the rest of us the potential downsides are glaringly obvious.
People are getting screwed by this right now in China and N.Korea. It is a real and present danger that may have ramifications for you or people you love in the future, and may even get them killed. McCarthyism was only 50 years ago, the Stasi 30, the Nazis 70. The Dutch inadvertently caused the deaths of thousands, maybe tens of thousands, of Jews by having a religious question on their census before the Nazis took over.
It happened before, it will happen again, and just because you don't know high school history, or simply didn't learn the lesson of it, doesn't make us extreme.
I think I am done :), you don't need to degrade the other person's intelligence to have a discussion. Or insult them. It is rude and unbecoming a member of this community.
When you continue to question whether people who are fearful are being rational, as if being fearful necessarily precludes that they have attempted rational assessment, you are the one being rude and dismissive of people’s intelligence.
I won’t even go into your absurd whining of the “extreme privacy movement” in the HN community, as if a huge part of HN’s audience aren’t daily optimists about the positive role and accomplishment of tech and data companies.
I don't think I need to explain the extreme privacy view, it is alive and well in this community.
