One problem I see is that if compensation for the product depends on the level of AI users, then there will be an incentive to lie, making the self-rating pointless. Also, it's doubtful the rating would carry through to the final product since it would be likely used for intermediate products used in the final movie/art creation, which is a different market than the end user viewer.
