Why AI art is so controversial

Until you get super fine-tuned AI's you will ALWAYS need human artists. AI just makes the initial brainstorming and pitching much much quicker. AI provides endless visualization for the initial concepts, the artist(s) then work on remaking and refining said image(s) to fit the actual product.

I know that the initial visualization is also an important skill to practice, but this AI thingy is very useful for projects with tighter deadlines AND budgets. It's up to laws and policies involving AI and copyright to decide how AI will affect artists as a whole.
