About the "art" I can't agree more.
About literature and poetry... I don't know how much the author is going to incorporate it, since magic in this world seems to be more based on sciency stuff in this world they are building, but a lot of settings use chanting as a mean of manifesting magic, and to do good chanting, poetry (which is part of literature) might come in hand, be it to make things more powerful (because magic?) or to make easier to remember stuff (which would be a nice use in this world setting, like, there are a lot of things in science that I remember I learned using music and poems, there was a nice one for sin/cossin stuff I never forgot).
