You still assume the artist in those examples is real. It could be a team, a ghost artist, etc - yea it's less likely than music, but still. The connection itself is quite difficult too, given the ease in which someone could plagiarize others work - sure they have mechanical skill, but did they really invest in the painting or was it ripped off from others ideas?
I suspect your connection to real artists won't be impacted. This, like the music example, just highlights our assumptions.
I'm not defending this AI garbage fwiw, i just don't think it's as interesting as most people make it out to be. I adore music, and i connect with songs i connect with. I don't typically think about the possible ghost writers, teams of writers, ghost players, etc. The music either speaks to me or it doesn't.
Though i'm not trying to connect to the musician as a person. However, as i was illustrating - if i really wanted to connect to musicians at face value, that ship sailed many, many years ago. Far before AI.
There are ways to mitigate this, but that balance will always be there - it was before AI, and it will be after. It's an evolution. Not an enjoyable one perhaps, but it is nonetheless.
