What that has to do with TSA Checkpoint at the airport? How many people go to through that checkpoint isn't dictated by how automated it is - it's dictated by how many people are flying.

All this thing does it speeds up process of you getting through TSA.

No faster than having a human hold up your id and compare it, plus now you don’t have yet another digital copy of your face floating around for the police state.

It doesn't, though. I haven't seen shorter lines or faster-moving lines at SFO, for example, since they implemented facial recognition. And it seems like they have the same number of people staffing the ID checkpoint as they did before as well.
