I sure do understand the request and need for AI as most people are not artists, sculptors, or 3d modelers. We could also interpretate the situation like one who is just using prefabricated models to pose, but never in a lifetime would be able to get one done. That is what poser per se is, a Pose program for prefabricated models. It can be compared like using a generative AI as the user will not really build up he's own designs and not own the prefabricated model, just using what is being offered. A sort of evolution with Generative Ai in a similar direction for the ones who do not have the sills to sculpt or rig for Poser/Ds.

I can't list the amount of tools and programs on one hand used to make a model poser/ds ready, just for the ones who like to use them, but in poser they are just prefabricated and set together into a scene. So I do not see a big difference between using Poser/Ds or generative Ai as both types are setting up given products into a scene. 

We could see it like this, the creative part are the ones who have the skills making the tools, or the models to be used in a posing program, others list there wish for what they want to be done. In Poser they say I want this outfit, this character, this Environment, this features, making it a commission, In AI they will ask for it in a same way to get the art they wish for, no big differences as someone else or something else made it for them after a request.  if it was not a request then we could interprete it " I had no Idea that I wanted it, but I take it because I like it " This in both Poser/Ds and AI. Either way the original artwork has been prior premade for the user that just likes to Pose the scene and does not have the skill building it from scratch.
