You knew it was bad, but it's worse
Thanks to these guys, everyone will soon know your name. The computers in the back room will just run a quick check of your face against social media, and the everyone will always know exactly who you are.
As I reported in the Observer, they are looking forward to selling facial recognition technology to retailers. That way, they can follow up with you online after you stop in offline (even if you don't buy anything).
The Moscow government already has it plugged into their cameras.
I've always pittied millenials and younger for being so used to seeing themselves named online. I don't think there is a pic of me online with my name underneath it, and I hope there never is. -But the culture is so different today, it's like asking people not to eat any kind of dessert or something...
Unfortunately, it seems this is an inevitable outcome given that advances in technology make this so easy to do.
You are not even safe even if you don't post pictures of your face online yourself. First, friends and family might upload group photos you were in and tag you in it. Also, since this data is so valuable to businesses, I could imagine stores automatically associating pictures of your face taken from cameras in their store to your identity discovered from your credit card payment, for example. And they would share this data with each other in a large quasi-public network, because it is mutually beneficial to them.
It won't be too long before everyone can easily find the identity of any stranger on the street just by pointing their phone camera at their face. And of course governments will go one step further and automatically and continuously do this process with publicly installed cameras that they have access to, and store that metadata of the history of where everyone has been at all times.
I unfortunately don't see any way that this future will realistically be prevented. It seems like the natural outcome given the projected path of technological progress and the individual self-interest of those with influence and power. Technology itself isn't good or bad. It is simply powerful, and that power can be used by people in good or bad ways.
