At the beginning of the Industrial Revolution there was a movement of "machine breakers", workers in industrial centres destroying new machinery in fear of losing their jobs. Their fears were not realised. Fear of AI is just a natural human fear of new technology. Even locomotives were feared at first.
Artists won't lose their jobs. Ordinary people don't buy their work anyway because they don't have enough money for it.
AI is simply a technological development. It can put various graphic studios etc out of work. But this is just evolution, there will be a need for new types of services and people will just do something else.
I wouldn't worry about the artists. Those with money will always prefer to buy an original work of art rather than an AI creation.
