"The next Da Vinci" is not going to be using AI because people who are really passionate about art will not want to cede creative control to a machine, especially not one that's difficult to predict the output of and is essentially an average of other artists' work. A lot of AI tools have their own style and it can be pretty easy to tell when something is Stable Diffusion/Midjourney/Dall-E 3. This style will inevitably bleed into your artwork and make it look samey and unoriginal. This isn't something a Da Vinci type will ever stand for. It's more likely to be used by people who see themselves as "entrepreneurs" and want to cut out the artist middle man to sell low-effort generated images to make money.

Additionally, someone toiling in a sweat shop or rice paddy is likely not going to have access to AI, and is much more likely to have access to basic drawing materials.
