Take a look at Super Auto Pets, a pretty successful and fun auto-battler game. It literally uses a free emoji pack for its core art. It doesn't really matter that they didn't hire an artist for those (though I think they did hire an artist after finding success) since a free emoji pack was enough for the creative product they wanted to create. If they had AI generated emoji instead, it wouldn't have really mattered much for the final result (creatively at least, I assume audiences would respond poorly due to GenAI's reputation). At the same time, the ability to create their product without paying a lot of money for artists was critical to make it in the first place.
This is what it means to me to "democratize creativity", to allow creatives to realize their creative ambitions in an area they are proficient at (e.g. video games) without requiring a lot of creative skill in adjacent areas that aren't critical to the experience they are trying to make.
