>> But 3D won't be free like 2D art, because the computational power to create high-quality 3D models dwarfs the computational power required for 2D. So it is safe to say 3D artists will not be 'deprecated' (rip 2D artists), for many decades.
"For many decades" lol, it's gonna happen within this year. There is already massive progress on this front.
