It's a stupid thing to be angry about because AI isn't about making art it's just doing that is a good benchmark because it's very visual and you can easily see at a glance how much more advanced one AI is than another one.
You really think that mega corporations are interested in art? If that was all AI could be used for no one would be researching it.
It's not necessarily for fine arts, but for cheap content generation.
For example, it can generate fairly accurate 3d models for environments and secondary characters without paying hundreds of people to do this manually. It can generate videos from text prompts without hours of human labor for filming, editing, post-producing, etc.
