As far as money goes... long run artists will still make money fine as people will value the people generated (artisanal) works. Just as people like hand-made stuff today, even though you can get machine-made stuff way cheaper. You may not have the generic jobs of cranking out stuff for advertisements (and such) but you'll still have artists.
The ones at risk (and complaining the most) are semipro online artists who sell one image at a time, like fanart commissions.
