1. (real illustration vs digital illustration)
2. (composing on sheet music vs composing in a DAW)
and
3. illustration vs Stable Diffusion
4. composing vs generative music models such as Suno
What's different is the wide disparity between input and output. Generally, art has traditionally had a closer connection between the "creator" and the "creation". Generative models have married two conventionally highly disparate mediums together, e.g. text to image / text to audio.
If you have zero artistic ability, you'd have about as much success using Photoshop as you would with traditional pencil and paper.
Whereas any doofus can type in the description of something along with words like "3D", "trending on artstation", "hyper-realistic,", and "4K" and then proceed to generate thousands of images in automatic1111 which they can flood DeviantArt with in a single day.
The same applies to music composition whether you are laboriously notating with sheet music or dropping notes using a horizontal tracker in a DAW like Logic. If you're not a musician, the fanciest DAW in the world won't make you one.
