Do you think there has to be an explicit disclaimer between what's AI-generated and what's real?

I recently came across a few images that seemed to be somewhere in the deep woods of the Amazonian forests. it was beautiful but I later realised it's AI-generated. Not to mention photographs of celebrities and politicians doing and saying things which seem too real but simply aren't... this lack of differentiator between what's real and not is quiet unnerving, especially if its "circulated" on various online platforms. What are your fears and speculations with AI generated imagery?
