I'm not sure whether you actually think this is good or bad but honestly I bet it would actually be a net positive, in a "if everybody's a pornstar, nobody is" kind of way. If you can generate nsfw video from a picture of a face with the press of a button, it will probably cease to be a thing that matters to anybody within a generation or two, in the same way we think about Photoshop today. It might be a bit of an awkward transition though since it definitely offends most modern people's sensibilities.

Lets be real though, it's the anime-style generation models that are going to be the pioneers in this field.
