I think this question sidesteps something even more fundamental. Pouring your heart and soul into describing a world through words is creative writing, and obviously has artistic merit in and of itself. Why is creative writing such an apparently unworthy art form, that all of that effort would be better off tossed into the trash, and replaced by a machine generation based upon it instead?
If you genuinely have the desire and capacity to write in depth about worlds, and things that happen within them, simply posting that writing would be wonderful. Visual mediums are not the end all be all of artistic expression, or human communication in general. I write comments and express my ideas through words all the time, and I appreciate when humans do the same for me in return.
Honestly if you have a tablet for long enough, the marks on the surface become pretty evident. Before my cheap huion tablet of several years finally gave out, parts of it felt like drawing on top of a vinyl record because the marks were so numerous and dug through the surface. In a way it was pretty cool to think about the amalgamation of all the strokes I ever used to create so many different things, all overlayed on top of one another onto a single "page."
