I don't mean to be flippant, and I wish you the best of luck in your creative endeavors, but I think the emergence of this sort of functionality will solidify the role of professional artists in our society. If you compare the work of art school freshmen with art school seniors, it's pretty apparent that using tools to physically create media is a pretty small part of what they learn.
And they've been drilled by experienced creative professionals full-time for four years. Many of the creative controls these generators abstract away are the most consequential, and they will never be more than an amalgam of what they've already seen. Smooth? Sure. Polished? Yes. Visually striking? Absolutely. Will every detail be considered, reconsidered, pored over, lightly massaged and then reconsidered by a team of people who've dedicated their professional lives to using images to elicit precisely crafted emotional responses in people? No.
That said, SyFy Originals and Hallmark Channel movies will probably operate much differently than they do now.
