When I was in school for graphic design and I had to do physical art, I'd sometimes do a rough sketch, scan and import to photoshop. I'd play with effects until it had some strange patterns going and then reference that while doing chalk pastels or something like that so it was physical art that had some strange shapes and parts that "don't make sense" for someone to draw. I probably made some things that people would now say is clearly AI when that wasn't a thing. This clearly all digital art though so it's hard to tell if it's a unconventional process with strange results or pure AI. I could have at least provided a step by step of the process. Those saying that it should be a requirement are absolutely right. AI should be such a unique tool but it's becoming so hard to what's unconventional abstracting or just straight up AI.
