You can't replace creativity (not yet).
And also
you can't will it unlike manual , algorithmic labor. So if you depend on creativity as your source of life necessities , you are pretty much at the mercy of outside circumstances. ( it is called being f****d )
Uh.. yes you can. Creativity is a skill you get better at with practice. And I don't mean graphic design, I mean inventing and improving the way things work. Manual, algorithmic labor has been replaced with robots a long time ago. Now it's all about doing custom inventive stuff that robots can't handle (even simple stuff like grabbing weirdly shaped lettuce leaves to place on a round bun)
