Art? Yes, you can get it to draw something in style of, but it won't be able to create new style.
I don't think that's true. Because DALL-E knows how to create art in various styles, it implicitly knows what are the parameters which separate one style from another -- for example, thickness or shape of brush strokes, degree of realism vs. surrealism, typical subject matter, etc.. I imagine if you asked some variant of DALL-E to create a new style, it could arbitrarily alter the parameters that define "style" and come up with something new, and even alter them in a way such that the new style could reasonably be expected to be pleasing/well-received.
