AI will certainly be a tool that artists use, but non-artists will use it too so very few will ever have the need to pay an artist for their work. The only work artists are likely to get will be cleaning up AI output, and I doubt they'll find that to be very fulfilling or that it pays them well enough to make a living.
When it's harder to make a career in the digital world (where most of the art is), it's more likely that many artists will never get the opportunity to fully develop their artistic gifts and personal style at all.
If artists are lucky then maybe in a few generations with fewer new creative works being created, AI almost entirely training on AI generated art will mean that the output will only get more generic and simplistic over time. Perhaps some people will eventually pay humans again for art that's better quality and different.
The prevalence of these lines of thought make me wonder if we'd see a similar backlash against Star-Trek style food-replicators. "Free food machines are being be used by greedy corporations to put artisanal chefs out of business. We must outlaw the free food machines."
