That ship has sailed. You no longer have a reasonable expectation of privacy in an airport. Courts have ruled that safety concerns override privacy considerations inside them. Alright, well, if this is the system we’re stuck with, then we might as well make it efficient. Now we have TSA PreCheck where you can give up all pretense of personal privacy in exchange for a relatively pleasant airport experience. And the facial recognition kiosks I’ve seen don’t seem inherently more invasive than having a human security guard doing their functional equivalent, and we’ve had that for many years.

I’m not thrilled about the situation, but feel powerless to change it. It seems like the majority of my countrymen think this a good tradeoff, so I can’t say I’m fully on the right side of the argument anyway. So if stuck with a system I can’t change, and most people don’t want to change, if this makes the practical experience of dealing with that system faster and less unpleasant, then fine. So be it.
