For now AI is a double-edged sword. On the one hand using it helps people who have no confidence in their own artistic styles to make something they would not have without AI help. On the other hand, it will cause people not to learn or develop their own skills now they have AI help. Over the long run I would say it will decrease the overall humanity's artistic creativity. But hopefully humans can develop something else to make up for the loss.
I have made my position against AI and it's role in the creation of hentai in particular, quite clear before, with the plagiarizing machine being capable of mediocre results at best so far, so I am certainly not a fan of it's usage in the medium.
That being said, the whole argument that AI is killing art is not so different to the conversation that people had about computer animation 20 something years ago when Pixar was out there making human models uglier than Inoda's abhorrent face. Nowadays, despite the sketchy track record that CGI has had with the production of anime in particular, no one can really argue that it hasn't become a legitimate art form.
Of course, there are a few differences with the comparasion, in particular in the pornography scene, where we so often find people who just lazily spread garbage content that they spent no time polishing after their shitty Deku Getting Pegged By Futa Yandere Toga piece of "art" gets spewed by AI.
What I see happening in the future, with my omniscient source of "I am making this shit up as I speak", is that people will continue to vomit out cheap and fast indie projects filled with lackluster AI, as they seek to appeal to the lowest common denominations out there (No hate to my homie Alter who enjoys some of the AI art out there) . Yet, more serious content creators will use AI like most anime companies utilize CGI nowadays, a way to spend less time and resources on certain things so they can focus their abilities somewhere else.
An example of this is background creation, a lot Korean manwhas straight up use a photoshop filter over an IRL photo of a background, before slapping in their work to save time. This is a perfect job for AI, which could plagiarize / generate a generic background in seconds without much issues
Don't mind the random push of my Sugu agenda while sharing an AI of her to seemingly relate this to all my previous yapping, while trying to steer this convo towards the actual point of this thread.
