I imagine for the younger generation AI images will have the opposite effect. People won't believe anything they see. Like here's a picture of young Trump attending a KKK rally but who knows if it's real
The thing is, we cannot fathom growing up and consuming media in a world where content generation is supported by AI. Younger generations may not even consider AI generation as a divisible construct from creativity. If they see a picture of Trump attending a KKK rally they will just see a picture and they will use other falsification tools to determine it's veracity.
People have said that truth doesn't mean anything anymore in this era but objective truth has long been meaningless in media because marketing does not produce truth any more than AI produces truth.
If you see something online, a picture or a video, that seems unbelieve or at least is unverified; do you go through any kind of internal falsification checks before coming to a conclusion of it's veracity?
The coming societal changes brought about by AI media generation are not unprecedented and visions of a chaotic future in which all creativity is somehow destroyed and objective truth is no longer achievable are really just us trying to imagine a world that is currently unimaginable. In reality, it won't be THAT much different then our currently reality. If you want a glimpse into our actual, banal cyberpunk future the best place to start is William Gibson's later novels. Things will be different but future generations will adapt just as we have adapted to the internet.
EDIT:
Like... if their qualms regarding AI are based on the idea that the processes of capitalism grind away creativity and are only interested in the money made from an end product... any imaginable future is going to be a bleak dystopia. AI existing or not does not change the fundamental realities of our currently political order. You aren't going to build "socialist AI" either. It is just another tool to be used for whatever means the craftsman wants, be that professional or personal. I genuinely don't understand where all of the left is getting all this doomsday prognostication from.
