Masks and temporary/permanent face altering techniques will explode as this technology takes hold. I think about it like ad-blocking, something that may work itself into the mainstream despite it's questionable ethics.
If the technology just stayed at facial recognition, maybe - I work on stereoscopic vision, so you'd have to change your head geometry too for my cameras if you're in parallax range..... and we're getting to the point of being able to do realtime skeletal pose analysis -- https://storage.googleapis.com/tfjs-models/demos/posenet/cam... So, it's an arms race :-/
I see what you did there :)
