Do we forget that not long ago everyone's name, address, and phone number was published in the phone book (unless you paid extra for an unlisted number), and hospital admissions were published in the daily newspaper. It used to be unremarkable, and now people shriek "privacy!!" when it's discovered that some mundane detail about their life is not a closely held secret.

No we don't forget.

Those systems were analog and could only be scaled to a certain extent, after which you ran into management overhead.

So in the example given by the OP, dominoes would not be updating your name in the directory.

That would be data that evaporated and never made it to record.

To increase the contrast - whole new types of clustering and analysis are now possible, at the moment a new data point is received.

Indeed, the amount and types of published information hasn't broadly changed, what has changed is the information horizon; the ability to search for information and analyse it. The world hasn't become smaller, our ability to see is much much wider. The information horizon is much further away from zero than it used to be (thanks to the computer's / big data's ability to communicate and analyse), and it's impact on society is much more than just privacy.

This reminds me of the decision on GPS trackers on cars: https://en.wikipedia.org/wiki/United_States_v._Jones_(2012)

Dreeben cited United States v. Knotts as an example where police were allowed to use a device known as a "beeper" that allows the tracking of a car from a short distance away. Chief Justice Roberts distinguished the current case from Knotts, saying that using a beeper still took "a lot of work" whereas a GPS device allows the police to "sit back in the station ... and push a button whenever they want to find out where the car is."

i once worked on a project (about 15 years ago) where we had access to a reverse phone book listing that was generated in part by having a copy of every distinct paper phonebook in the US (also things like school directories) sent overseas to be hand entered (2-3 times for QC). A "nice" feature of it was that the address info was also geocoded so we could answer questions like "Who are my closest 100 neighbors and what are their home phone numbers?". Between that and Google buying the archives of usenet[1] in the same basic timeframe I realized that if it's written down its not likely to stay private for long.

The phonebook was a paper-based system, with significant costs to look up and act on information at scale. You needed the books, the researchers, and the time to find and act on specific numbers.

The numbers weren't widely cross-referenced across multiple other identifier databases: shopping, driving, voting, location to 1m accuracy and 30s time precision.

Every household, small business, mafioso, or political operative didn't have a full copy of the archive, and the ability to deploy it at a moment's notice.

Or in short: scale and costs matter. In fact they dominate all other effects.

Your objection is both meaningless and betrays a profound failure of undrestanding and sympathy.

"Do we forget that not long ago everyone's name, address, and phone number was published in the phone book [...]"

The phone book is an opt-in system, with the ability to remain "unlisted". There's absolutely no such choice, though, from these modern, private data collectors. And they're everywhere.

Consider the following hypothetical: A battered wife flees her husband and takes shelter in a shared house run by a women's organization.

In your phone book world, she didn't need to dramatically alter her existence to stay safe. She could continue to maintain a reasonable subset of her professional and social relationships. She could get a new job in a new city. She could buy groceries. She could pay her own electricity bill. And she definitely didn't need to take her life in her hands to order a cheese pizza.

In this brave new world, though, her ex can track her with the utmost ease. She has to shed nearly every piece of her modern identity -- reconfigure apps, wipe her phone/laptop/tablet, stop using sites that geolocate via IP, and halt nearly all interactions with the modern economy -- at significant social cost.

The sheer number and diversity of data collection points -- and their increasing necessity to participate in the digital economy -- makes opting out orders-of-magnitude more difficult. Yours is a false comparison.

It's likely the locality / ephemerality / repudiability of those identifiers made them less of a big deal in an era when people couldn't instantly look these details up or build a detailed profile of everybody given the right data sources.

Wait hospital admissions? Really, why?
Re:Ask HN: Who really gives your personal info to Intelius, ... by lucb1e on Tuesday March 07, 2017 @05:03AM (#13809358)
I imagine your friends didn't tweet or message a Telegram group about having had an accident back in the day where that was common (whenever that was, I've never seen it). When the telegraph is the fastest method of communication and landline phones are expensive, you might not learn about a friend being in the hospital until word of mouth reaches you.

Not saying this is the one true answer, but I don't find it hard to imagine why.
