Whenever a powerful technology is invented, it creates an explosion of different effects on society that are impossible to keep track of.
Perhaps you're right, that it will bring positive effects. Although we have to remember that women will watch AI porn too. The reason women are less inclined than men to watch porn is because it's visually-based, and the storylines are awful.
This may be a stretch, but I believe that AI porn will eventually be capable of creating porn experiences with storylines as complex as those found in erotic novels. And just think how much women love erotic novels (How many copies did 50 Shades sell again?).
As for deepfake pornography, that's another unstoppable force. The best measure we have against it is to make it illegal. Yet how could such a law even be enforced? How could we ever keep track of which porn is deepfaked and which is not?
In the end we will simply accept that our social media images can be used to put us into pornographic scenes. People (mostly dudes) will make deepfake porn of their boss, their colleagues, the cute girl they saw from across the room at the cafe and their best friend's wife. And there won't be much we can do to stop it.
