Rembrandt would argue that he was a craftsman, although some of the liberties he took in stuffing his paintings with hidden innuendo and symbolic jokes at the expense of some of his clients, definitely makes many of his paintings works of art.

Alas, only when taking a shirt at MacDonald's becomes equaly obsolete, and it has been made apparent that any task or job humans do could also be done by technology, only then will it help the artist in your example with their artistic career.

It is remarkable, when you think about it, that artists seem to be the first people that are made to feel obsolete. There are plenty of jobs that could have been fully automated, steampunk-style, from the moment the industrial revolution took hold.

Maybe it becomes slightly less remarkable if you take into consideration that collecting/investing in art has always been an integral part of people of considerable wealth. Even if they did not care much for it, didn't understand any of it, or were only motivated for the money,... regardless of your field, being very wealthy forced you into developing at least some connection with art. The billionaires in tech all seem to be an exception to this rule, and their lack of any connection with art, may have made them feel that art is easiest of all to replace using generative software. And for them, this was probably true - and they lack the connection to have developed any taste or eye for quality in art, so they're easily pleased with something a computer makes for them.

If only the artists are actively excluded though, people in other jobs will never fully appreciate that given the effort, their job is just as easily automated. Once people in every possible job have been made to feel just as obsolete, the world may be ready to order itself based on individual preference and mutual appreciation of whatever it is you choose to do 'for a living'.
