I've read an infinite amount of comment about that but never heard of a single convincing example
Most publically consumed art is made by large teams, which naturally leads to a dilution of a singular artists vision. With the current quality mass media, I'm excited to see singular geniuses with the power of whole production companies at their finger tips.
If you can't afford to pay real artists to draw for your comic book, maybe you shouldn't be in that business?
Obviously, AI training data is a touchy topic. I completely agree artist should be compensated. To what degree is a hard question.
As to whether or not I should be making comics- I have story to express and there are tools available to express it. I really don't care what you or anyone else thinks about the validity of that expression. That's what makes it art. You talk like someone who has never produced art.
Others will feel differently, and that's ok. I find myself not even mad at such florid proclamations as to the death of the human spirit. Such sanctimonious proclamations were made by portrait artists at the advent of photography as well, and yet here we are, Art intact, all these decades later.
