This is 100% a hacking and extortion/blackmail/propaganda tool. Aside from entertainment I'd love to hear of a different use case...
Now imagine what happens when indie film directors have access to the same tech, which simply requires learning these tools.
I'm not dismissing the very real and very legitimate concern about how deepfakes can be (and are being) used for blackmail, extortion, and propaganda. But I wouldn't discount the legitimate uses.
