Of course it will. Their employment isn't sacred. They have a skill, we're teaching that skill to computers, and their skill will be worth less.
I don't pay someone to run calculations for me, either, also a difficult and sometimes creative process. I use a computer. And when the computer can't, then I either employ my creativity, or hire a creative.
Okay, but that's a different argument from your original. First you said "only bad artists will lose their jobs," now it's "good artists will lose their jobs but I don't care."
I also agree that artist employment isn't sacred, but after extensive use of the generation tools I don't see them replacing anything but the lowest end of the industry, where they just need something to fill a space. The tools can give you something that matches a prompt, but they're only really good if you don't have strong opinions about details, which most middle tier customers will.
