But he said "a proper facial recognition system".
His point is valid in that specific, restricted area.
As in, a facial recognition system that does not just a picture, but LIDAR technology or somesuch to create a 3D map of the face on top of visual cues.
That should prove more difficult to cheat, whatever makeup you have.
Of course, if you go putting Silly Putty on your face and makeup on top of that, then all bets are off.
I guess facial regocnition is just doomed from the start.
