And then "one president became another president"

Computer graphics analysis and understanding is evolving at a speed that is really scaring me. A paper recently published in the 2015 edition of the International Conference on Computer Vision (ICCV) showed how to process a video with gestures from a person and then create a 3D computer graphics model of another person doing the same gestures.

In the video that can be shown in the following LINK (from minute 1:07 onwards) a 3D computer graphics model of a U. S. president makes the same gestures as those made by another president.

There are moral implications for me in this scenario.
