"put their faces in a recognition database"
Just so we're clear and can read past the headlines. This database doesn't exist and there has been no evidence that a database built off of meta ray-bans exists. And I would obviously dump the ray bans if this was actually a thing.
Doesn't it?
The technology exists to build it. The pipelines exist to populate it. The marketing engine exists to leverage it for targeted delivery of content.
And yet, somehow, nobody's built it?
How sure are you of that?
Facebook itself is such a database, is it not?
I mean, it's literally in the name?
