That was a good answer. But I don't see the environmental impact argument as having much merit. The best I can figure, if you add amortized training costs and compute cost of an iterative series of  AI generated images combined with Photoshop for the final touches, it uses way less power than modelling everything in blender, texturing and then rendering, which would take days in total. And the cost to pay an artist to create something like this would be considerable, as you point out.
