Well, I can expect then a lot of issues regarding copyright and intellectual property infractions.
AI is not generated out of nothing, is a miss and match from images taken from the internet, so you may get sued if someone's work is identified and the author hasn't provided any rights or permission to let other individuals to use their work in a certain way, as well, several webcomic platforms demand that your work is yours and should not infringe another person's copyright, trademark or intellectual property.
So I can imagine several webcomics generated with AI trying to make their way in Webtoon, Tapas and other platforms, just to get taken down by constant reports and emails from fellow creators within the platforms or legal action from the original artists.
We as content creators are going to always be fighting against the new entertainment, no matter it's shape, if it's human, human-made, etc. Maybe I'm too dead inside, maybe I'm just vibing and living a well deserved chill life, I don't know. But to me this ain't the end of the world
