Face Swapping

I always think it is interesting to see the evolution of technology.  Some tasks seem impossible.  Then someone figures out how to do it and for a little while only scientists can do it.  Then it finds a business case and only people with a lot of money can do it.  Then eventually it gets to the point where everyone can do it and what was once magic becomes common place.
This seems to be what is happening with some video manipulation technology, in the case of the video here, face swapping.  Yes, the ability to put one person's face on another person's head in a video.  It turns out that for some time, Hollywood has been able to do this.  Soon, you will be able to do it too.  Check it out.
