This website contains age-restricted materials including nudity and explicit depictions of sexual activity.
By entering, you affirm that you are at least 18 years of age or the age of majority in the jurisdiction you are accessing the website from and you consent to viewing sexually explicit content.
That is the default model behind copyright, which basically says that the only things people can use your copyrighted work for without a license are those which are determined to be “fair use”.
I don’t see any way in which today’s AI ought to be considered fair use of other people’s writings, artwork, etc.
The concepts contained within a copyrighted work are not themselves copyrighted. It’s impossible to copyright an idea. Fair use doesn’t even enter into it, you can read a copyrighted work and learn something from it and later use that learning with no restrictions whatsoever.
