Kind of a strange question - what do you mean by "turn into movies"? Like an AI will just take random novel X, and use technology to make a full-length feature film out of it, complete with sound effects, visual FX, music, etc...at the press of a button? Or do you mean it will take a novel, figure out the plot, important events, salient points, etc... and make a feasible rough draft of a script or screenplay? The latter will happen much earlier than the former - I would guess that numerous Hollywood studios are using that sort of tech already as a drafting tool or something along those lines. There's also some sort of writer's strike happening at the moment in the face of this new tech, so I'm sure a lot of studio execs are chomping at the bits to be able to downsize their writing teams (for both TV and for Film) and still retain the same productive output.
