I think your situation is different, in that a) people who spend many years learning to be good illustrators tend to have standards for what they create in ways that, say, virulent racists using ML tools don't; and b) people rarely take illustrations as evidence of things that happened in real life, whereas they will do that with ML-generated fake photographs.
I think, like Paul Graham would say, we'll develop societal antibodies against this.
And, like Sam Altman would say, it is going to be net good for society, but that doesn’t mean there aren’t bumps along the way. We will need to learn to navigate them well.
