There is plenty of companies already firing people due because of AI, or at least, that's why they proclaim.

There is also plenty of freelance / artistry type people who would of had work before (i.e creating Halloween, mothers day, Easter, etc) promotional material which is now just outsourced to AI. You see some of the biggest companies on Earth posting AI stuff for special event, etc.

Most aren't at the stage of using full AI "art" for advertisements (except maybe Coke) but some of these companies would already have full time artists, which they've bypassed. Their jobs are not forever and eventually will get killed.
