I saw that article. It's a pretty ingenious way to process people. If you've come back into the US, you get your retina scanned and facial recognition performed at the kiosks. It's already happening, and has been for years.
What people need to realize is we have remarkably few "privacy" protections written in law. Things like HIPPA are rare. Most of these laws haven't kept up with technology and this congress is in no mood to update them, so many protections are slowly slipping away.
What people tend to mistake for privacy is anonymity. You can go to a strip club and if nobody knows its you, and no record is kept, you have achieved anonymity and nobody will find out. But with that little bugger in your pocket, google will probably be asking for a review of the pink pussycat before you leave.
Anonymity is what we are losing. We never had privacy. We had the ability to go about our lives with no record being kept and no name associated to our actions.
I am SO grateful that I grew up before the age of social media. All the stupid, moronic stuff I did growing up is lost to all but memories of a few people. And even more is lost to just my memories. Today, some frenemy would have pics going around before I woke up.
