I am rather enthusiastic about IA art, but I agree with the fact that it's a shame for people to use it and pretend it is their own creation. I also agree that it doesn't have its place on this community, as it is a community for artists to share their personal creations. I think that an easy way to differentiate between the creations of AI and people is to be able to see the process. (but also by seeing the spectacular and sudden artistic evolution of the person)
But I didn't agree with your point of view about AI art and its issue ;
A piece of art is seeing by million of people - who will keep this inspiration in the back of their minds, until the day they use it unconsciously or not to create themselves their own piece of art, and maybe sell it after. It is basically the same process as AI for my opinion.
So I personally don't have any problem with that, but I can understand the anxiety of artists in relation to all this.
