Right now it is not a tool. Right now it is an attempt at replacing artists.
It could be implemented in existing softwares in parts to make it a useful tool. Like a tool that could easily recolour parts of a fully rendered illustration, while still respecting the artistic intent with the form and lightning.
But right now it just spits out the blandest stuff, based on what it has identified as the most common denominators in art.
I understand the excitement, but it is very much a situation of a layman trying to describe to experts what the expert and all their peers need.
I think it is just because AI has been hyped so much, and has genuinely made such impressive progress that people get swept up by the excitement, and idea that they could make their ideas into something tangible. They just don’t know the amount of consideration that goes into translating that.
Right now AI art is like Google translate poems.
