I'm going to keep repeating myself because your responses are so basic it's actually hilarious reading them.
One more time ... There will come a point in time where humans will not be able to decipher what is generated by AI or not.
When this happens, people will be watching and enjoying "AI art" without even caring or thinking to themselves ... "Was this created with AI?", people won't know unless it's disclosed as such.
That's the issue. If no one knows, everyone will question.
If AI film becomes more mainstream and accessible, people will begin to assume everything is AI until proven otherwise.
I seriously doubt anyone will pay for something anyone can cook up with a paragraph long prompt and a computer.
