Just like https certificate authorities, the only way to fight all the AI slop will be "trusted" camera firmware that signs every image with a full chain of trust that the output was a real physical video taken will a real device at a real location.
Counterpoint: this will kill all whistleblowing and investigative journalism. All sources revealed in an instant. We already had it bad with the printers.
If AI is a concern mandatory AI fingerprinting as currently implemented is better.
