First of all, and most relevant to the discussion, that website handles single pictures. They don't do videos, which means I can pedantically classify the result as a "photoshop" instead of a "deepfake".
As for the results themselves: I uploaded a couple pictures of me. I can't see the full result because I am not a paying user, but even in the blurry preview I can see that it's a fake. One of them even fused my clothes and my skins, which I guess could be a turn-on for those who are into Lovecraftian horrors.
I won't deny that it's technically interesting, but I wouldn't start a moral panic over its results.
Whatever happened to mystery, and desire, and letting your imagination run wild trying to fill in the blanks?
It's like the computer is being used to narrow our horizons, not broaden them.
