The market of people who care enough about those aspects to pay an expert is, I'm guessing, much smaller than the market for people who will be fine with whatever they can come up with themselves.
If we can have an infinite variation of personalized stock photos, I'm betting that the "good enough" side will win.
I'm still not scared about my job since I provide specific solutions (C++ architectures) that an AI cannot produce (yet), but it's worrying for everyone and every kind of job at the same time.
If you don’t like the taste of the people who want to pay for art I suggest doing what is traditional and either (a) paying for it yourself, or (b) taking over or setting up the government funding for artists so that people who share your taste are in control.
They do if they lose their jobs. Art isn't something you must buy. I like to buy art, but if I lost my job, it's one of the first things I'll be cutting back on. And the less people are buying, the more the remaining artists have to charge to keep being able to afford to do art, which just spirals more people out of the buyers market.
