I can create and explore realities using my imagination alone, though. I personally don't think having it become actual 2d or 3d art will have a lasting impact. It might be fun for a while, but it will get old.
It's kind of like your imagination on steroids as the system creates worlds using you imagination as the seed and augments it with summation of all the human creations used to train the network. Give Stable Diffusion a sentence for example, it will create something way beyond what you could of imagined and/or created on your own.
