Yes, especially in propaganda. The statement that it could "allow anyone with similar tools to take a photo of a person found online and make them appear to say whatever they want" is scary.
However it won't be able to pick up someone's mannerisms from a single picture, so it will be possible to figure out that it is a fake. But it won't be immediately obvious to people who've not watched that person extensively, and before it is labeled a fake the damage will have been done.
We watched a movie the other evening that had an actress in it that we saw in a multi-season series several years ago. We'd seen her so much that when she made a particular move in this movie we remembered that move from a specific scene in the series. So if someone took a picture of her and made it into a video we might be able to say it is a fake. But even then it is a subjective call and there's no proof.
