I suspect it's less about being puritanical about violence and nudity in and of themself, and more a blanket ban to make up for the inability to prevent the generation of actually controversial material (nude images of pop stars, violence against politicians, hate speech)
Put like that, it's a bit like the Chumra in Judaism [1]. The fence, or moat, around the law that extends even further than the law itself, to prevent you from accidentally commiting a sin.
I am guessing a movie studio will get different access with controls dropped. Of course, that does mean they need to be VERY careful when editing, and making sure not to release a vagina that appears for 1 or 2 frames when a woman is picking up a cat in some random scene.
We can't do narrative sequences with persistent characters and settings, even with static images.
These video clips just generic stock clips. You cut cut them together to make a sequence of random flashy whatever, but you still can't do storytelling in any conventional sense. We don't appear to be close to being able to use these tools for the hypothetical disruptive use case we worry about.
Nonetheless, The stock video and photo people are in trouble. So long as the details don't matter this stuff is presumably useful.
I wonder how much of it is really "concern for the children" type stuff vs not wanting to deal with fights on what should be allowed and how and to who right now. When film was new towns and states started to make censorship review boards. When mature content became viewable on the web battles (still ongoing) about how much you need to do to prevent minors from accessing it came up. Now useful AI generated content is the new thing and you can avoid this kind of distraction by going this route instead.
I'm not supporting it in any way, I think you should be able to generate and distribute any legal content with the tools, but just giving a possible motive for OpenAI being so conservative whenever it comes to ethics and what they are making.
I've been watching 80s movies recently, and amount of nudity and sex scenes often feels unnecessary. I'm definitely not a prude. I watch porn, I talk about sex with friends, I go to kinky parties sometimes. But it really feels that a lot of movies sacrificed stories to increase sex appeal — and now that people have free and unlimited access to porn, movies can finally be movies.
Good luck generating anything similar to an 80s action movie. The violence and light nudity will prevent you from generating anything.
