Think a layer deeper how can it misused to control naratives.
You read some wild allegation, no AI marks (they required to be visible), so must written by someone? Right? What if someone, even the government jumps out as said someone use an illiegal AI to generate the text? The questioning of the matter will suddently from verifying if the allegation decribed happened, to if it itself is real. The public sentiment will likely overwhelmed by "Is this fakenews?" or "Is the allegation true?" Compound that with trusted entities, discrediting anything become easier.
Give you a real example. Before Covid spread globally there was a Chinese whistleblower, worked in the hospital and get infected. He posted a video online about how bad it was, and quickly got taken down by the government. What if it happened today with the regulation in full force? Government can claim it is AI generated. The whistleblower doesn't exist. Nor the content is real. 3 days later, they arrested a guy, claiming he spread fakenews using AI. They already have a very efficient way to control naratives, and this piece of garbage just give them an express way.
You though that only a China thing? No, every entities including governments are watching, especially the self-claimed friend of Putin and Xi, and the absolute free speech lover. Don't think it is too far to reach you yet.
