I remember when the first round of capacitive buttons showed up. I can’t find it anymore, but there was an article on a fan site for MP3 players I read in 2010 that showed the comparisons of physical vs capacitive vs touchscreens and capacitive buttons only had negatives. It baffled me when they just never stopped using them on things. That article was burned into my mind and now I see that logic has spilled into a thousand other industries.

Those fast track lines at the airport I recently read somewhere is supplied by a private entity, which means all those face scans are just added into a database for future surveillance.
