The fear I have has less to do with these taking jobs, but in that eventually this is just going to be used by a foreign actor and no one is going to know what is real anymore. This already exists in new stories, now imagine that with actual AI videos that are near indistinguishable from reality. It could get really bad. Have an insane conspiracy theory? Well, now you can have your belief validated by a completely fictional AI generated video that even the most trained eyes have trouble debunking.
The jobs thing is also a concern, because if you have a bunch of idle hands that suddenly aren't sure what to believe or just believe lies, it can quickly turn into mass political violence. Don't be naive to think this isn't already being thought of by various national security services and militaries. We're already on the precipice of it, this could eventually be a good shove down the hill.
