Well, presumably, if it is your computer, running your program, using your equipment, you've got the copyright until your computer gains consciousness and a lawyer capable of filing a lawsuit.
The problem isn't really about using it yourself, it's that people don't need to ask your permission to use it, therefore you can't (easily) profit from it. Possibly quite annoying if you're in the AI business.
I admit I was being somewhat facesciuos. But clearly If you took credit for the work your computer did running your program, you would probably not get an argument from your computer until the conditions I mentioned were met

It’s when then computer creates the art itself that it becomes the artist
