That's why I put "real threat" in quotes ; I was paraphrasing what I consider to be the excessive focus on FR

I'm a security professional. FR is not the easiest way to track everybody/anybody. It's just the most visible and easily grok'd by the general public because it's been in movies and TV forever

To whit, FR itself isn't what makes it "easy", but rather the massive corpus of freely available data for training combined with the willingness of various entities to share resources (e.g. Sharing surveillance video with law enforcement).

What's "easiest" entirely depends on the context, and usually it's not FR. If I'm trying to identify the source of a particular set of communications, FR is mostly useless (unless I get lucky and identify, like, the mailbox they're using or something silly like that). I'm much more interested in voice identification, fingerprinting, geolocation, etc in that scenario

Again, FR is just...known. And visible. And observable in its use for nefarious purposes by shitty governments and such.

It's the stuff you don't see on the news or in the movies that you should really be worried about

(and I'm not downvoting you either; that's for when things don't contribute, or deserve to be less visible because of disinformation; not for when you disagree with someone)
