What is the difference between AI scanning existing art, and creating new images informed by the prior art, and a person touring galleries, looking at the works

What is the difference between AI scanning existing art, and creating new images informed by the prior art, and a person touring galleries, looking at the works of living artists, and creating new works influenced in style, color, framing, etc. by those works? Should the works of a new artist be beholden to all those whose works they have looked upon? As another thing to consider, is there any rationale for copyrights on music (in particular) that wouldn't equally apply to the recipes food dishes created by cooks? Both build upon the works, style, ingredients, etc. of those who preceded them. Seriously interested in the arguments one would make for copyrighting music that wouldn't stand equally well for recipes.
