Personally, as an artist who spends the vast majority of their time on private projects that aren't paid, I feel like it's put power in my hands. It's best at sprucing up existing work and saving huge amounts of time detailing. Because of stable diffusion I'll be able to add those nice little touches and flashy bits to my work that a large corporation with no real vision has at their disposal.

To me it makes it much easier for smaller artists to compete, leveling the playing field a bit between those with massive resources and those with modest resources. That can only be a good thing in the long run.

But I also feel like copyright more often than not rewards the greedy and stifles the creative.
