I think it's worth remembering that all of these AI's work by having an unbelievably large number of weights. So many weights that it's all an uncontrollable black box. On the other hand, your work is all about having control, and I don't personally expect your work to lose value for this reason.

Another thing to think about is what the AI is designed to do. Without knowing the details, I would expect it to be trained to produce the 'most likely' output given the prompt. Consequently, I would think being inventive is against its design, and 'most likely' is effectively that same as 'average'.
