There would still be a long way to go, I believe. Creating a consistent art style, with assets that fit into each other well for a whole game world would still be very challenging, for example.
We are definitely getting warmer. Exciting times. I would love a metahuman like diffusor for my characters. This would also be great for quickly generating props from photos or midjourney conjures. I still feel like all of these techniques and tools still require an artist, but the artists job is now more macro than at the micro. Awesome!
All that remains is a network for rigging (and maybe retopology)
Indie gamedev would be revolutionized
