uh it's a tool?
it's not really useful when you're trying to learn art. but I can see how it could be used in a way to fit in an art process.
the real problem is not depending on it to the point of it's doing all the work, and you can't decipher what it's outputting and not having complete control over what it outputs.
that's already a concept with 3d animation, where you can pose your model, make frames, press play, but if you don't understand how the program interlopes your frames, you're going to be fucking lost and waste time. you have to be able to look at this and know what will happen to your animation when you fuck around with the bars:

(2d people don't have to deal with this, they just
"unga bunga I draw frame, then nother frame, then nother frame, then noth-", the biggest advantage of this is you can iterate and make controlled drastic changes faster and focus entirely on the idea, that shit above is like looking at the matrix code, it's hard to understand at first, but it gives you more control over timing and you can adjust shit)
I never understood the problem with full hate from non artist trying to make the point that AI should make Artists upset.
it's kind of like saying I should hate 3D tools when I invested more time into 2D tools, and 3d does some things faster.
But the thing is, a lot of those same fundamentals like how lighting works, composition, anatomy, animation carries over to 3d
and if you already know a good amount of 2d, you'll only add to your skill set on top of being able to do some fuckery like bringing 2d ideas into 3d and being able to run circles around someone who just has a 3d background.
AI will eventually be how 3d and 2d can play off of each other and still maintain that level of control without losing the interactive aspect.
