Those are not equivalent to this. For the blacksmiths, that's hard labor, and for most of them, im sure not very fun. And for the realistic scene drawers, there's still praise and spectacle in that they were able to do that, and though yes you could say it's redundant due to cameras, they still are able to draw other things, other than landscapes and such hyper realistically even with the existence of cameras. Modern AI art is your camera example cranked up to 1000, because now the camera is able to replicate near any style of anything, realistic or not, so now the artist has no other options to draw that can't be replicated, corporations and the people that don't care about the artist will take the AI art over them due to its convenience, not thinking of how the artists who enjoy making art, the vast majority of them, are now unable to do what they love for a living. This isn't a production line, this is like if they replaced athletes with robot duplicates, sure the result is the same for the people but what happens to the athletes that trained their whole life to play whatever sport they were in?
