The creepiest is that whenever there is a discriminant network for judging/identifying sth, there is a generating method taking advantage of this network to make artificial one to fool the network. That means, one day we can take advantage of 3d-printing to make face masks to disguise as anyone, making anyone's voice, and making anyone's handwriting. The existing identity system will total break down.
(I'm from China, here exists a kind of company which loans to you solely by ID card scan and webcam verification. Just imagine one getting lots of loan using stolen ID cards and artificial realtime face swapping videos and artificial voices)
Apologies for bad English
