It depends DON'T YELL AT ME HEAR ME OUT
I'm an artist. I take commissions. And sometimes, I've had clients come up to me with references and genuinely say "I found this on pinterest/google, and it fits my character, I just don't know if it's AI. If it is, I hope you don't hold it against me."
In that case, I gently tell them that yes, it is AI, and no, I won't hold it against them. For artists, it's easy to tell, but since most of my family and friends can't draw, they have a hard time recognizing AI for themselves.
The fact that they are coming up to real artists to draw their XYZ, to me, shows that going to AI to 'create' isn't their first instinct and thought.
But in the end, follow your gut, it's usually right
