This is something people always miss in these discussions. A graphic designer working for a medium marketing company is replaceable with a Stable Diffusion or Midjourney, because there, quality is not really that important. They work on quantity and “AI” is much more “efficient” in creating the quantity. That too even without paying for stock photos.
High end jobs will always be there in every profession. But the vast majority of the jobs in a sector do not belong to the “high end” category. That is where the job loss is going to happen. Not for Beeple Crap level artists.
