So, I would expect them to have captured a seriously significant AND deduplicated (through the iris) database of faces as well.
Obviously, this is an extremely valuable database on its own merits, because it contains biometric data on a ton of people from "non-restricted" countries and may well solve some of the systemic biases current biometric systems show, due to lack of a representative dataset to train on.
These systemic biases are currently one of the major arguments _against_ the use of biometric systems at an even bigger scale and thus solving it will take away a big tool in the privacy-rights activists toolbox.
Are biases still systemic if at one point a significant amount of people from every geographical location on the planet has been included in the training set?
I can imagine arguing _for_ this position at the very least becomes a lot more complex.
