You could use those things to assist an attack. It's been done many times. But they just don't scale. These types of tools scale. Also I'd love to see someone realtime fake their identity with Photoshop or a pdf editing tool. Seriously send me links I'd love to see it
Aside from entertainment, what's the use of Adobe Premiere? Or Davinci Resolve? Seems odd to exempt the one use case that this is most valuable for. Look at how many Hollywood movies had their CGI improved by fans using this kind of tech and a laptop.
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.
