Hmm, isn't that a little like saying "now that we have cameras, no one needs to paint any more!" AIs can generate realistic video and images, but for me the fun of generative art is that it isn't realistic, it has texture, you can get a sense of what kind of patterns it will make, like echoes of the algorithm. Sure, you could probably prompt for some kind of geometric image, but if you asked for a little script that made them, then you could make tweaks and see what happens...
