The thing is, generative AI isn't doing anything that human creators don't. Yes, it's drawing from a huge library of content that it's been trained on, just as humans do, but the results are novel enough to pass any legal test in terms of copyright.
The uncomfortable reality is that all artists assimilate disparate influences in the hopes of generating something novel. AI may not be able to do it with purpose and intention and meaning, it may be based on a random seed, but it's still creative in a very real sense.
And what we have now is just in it's infancy, stupid text prompts correlating based on tagging, but eventually it will be a tool for artists, not a replacement. It will allow for the kind of finer grain control and tweaking that will vastly speed up the process for realizing art, and open fine art up to less technically skilled designers. People will find a way to use it to do things they simply couldn't on their own. I'm especially interested to see the impact it will have on animation
