There used to be debates about whether face recognition should be allowed at all. In 2017 an executive order rolled it out at airports, where it's now used by the CBP and some airlines. The TSA is now considering using it. The debates are over, it's happening and there are now articles about how convenient it is to board without a boarding pass. The definition of normal continues to shift slowly towards universal surveillance. Every little increment is enabled by a few years of the previous increment being normalized and a morsel of security or convenience.
