If the autocompleted part were copyrighted, why would you be able to use it freely? What claim to you have to authorship? Did you, perhaps, write the stuff that the autocomplete used as context to give you a selection of choices to make about what to put there? Because that still sounds like a human making choices about things to me. This is a vaguely recognizable metaphor for prompt engineering, but I think you're orders of magnitude off in estimating the ratio of human choice to computer extrapolation. Sure, a compiler or something maybe is a better metaphor, but even then the concept, the source material is generated by a human. You could say that a prompt is source material and the generator is just a compiler analogy, but I think they made the only choice they could here. Otherwise you can use a generator to make literally a billion images, copyright them all (including aspects you did not make a choice to add, like details on people in the background there), and control art for the rest of time.
