AI inpainting has been around for a while and it's not going away. This has been trivially possible with opens source software on decade old consumer hardware for about a year now, much older hardware if you're patient. I just don't see what sort of governance can be realistically put in place to police the creation of such media, and we already have laws against disseminating it.
