I understand the hypothetical dangers of an AGI with the "wrong" reward function where "wrong" includes "like humans in terms of species-tribalism and intelligence-smugness", but I don't actually see a media generator AI necessarily having human-esque identity that you're suggesting.
For the entertainment of the creator. Maybe you are right that AGI will be entertained by watching humans turn into vegetables as they aimlessly watch a screen for hours at a time, but I suspect not.
Maybe let's hope that a hypothetical AGI finds us "cute".
AGI might have reason to keep us alive, sure, but why create media for us? Given our current trajectory, AGI will be very energy hungry. How will it justify using that energy for the sake of human entertainment?
