Art & censorship
Always a problem
Obviously there are some legal restrictions - in UK not even remotely photorealistic stuff e.g. cartoons, can be regarded as kiddie pron & would still be a massive legal offence (though some artists, e.g. Belmer, have made a career / cash from creating things your average member of the public would serve jail time for) *
But beyond the obviously illegal, always a slippery slope as lots of people will use this to create art (you may lack painting skills but if you can craft an appropriate phrase AI may do something you would have liked to paint)
I like a variety of artists, but being UK based may as well reference "recent" British artists where some of their works have caused controversy, I imagine the moderators would not like images that resemble some pieces by Bacon, Freud, Jake & Dinos etc.
I can see all these art AI companies going the chocolates box cover art style only.
* Remember seeing some Belmer** stuff in the UK years ago (I did not enjoy it, but looking at challenging art sometimes does make you feel queasy), not sure if it would still be allowed with current rules as the old art / pron argument never goes away & sometimes curators go the path of least legal resistance.
