I think humans having a platform to tell the masses to "be worried" is as troublesome these days as AI content. mass media that can be manipulated has been around for 100 years. I don't think AI is unique.
It's fairly trivial to write code that can autogenerate hundreds or even thousands of AI-generated videos using Veo 3 with individual characters to push any narrative you'd like and push to Instagram or TikTok.
That's way scarier to me than a newspaper having a bias, or someone with an audience publishing a controversial blog post.
