Even that I do not feel like using AI for Art, does not mean that I hate AI, or would ever start making any accuses of theft, it is what it is, some prefer using this method for there Art others use other kind of methods, at the end it is up to the creator how he will make the presentation and what tools he wants to use. 

AI does not disturb me per se as it can also give you Ideas for Models, or how you could Improve these, so it is not all negative and dark. I do not get the feeling that it would place me into a corner, or making me worry that demands for 3D models would just stop. My experience shows that contrary is happening, the more AI is thrown out the more unique a traditional artwork will be and the more value it will receive. I do look at the AI generated art, how could you avoid it ?! But the only thing that it influences is to make me try to produce 3D models that have just as  much quality and be easy to use for traditional art.

If the Creator or artist just scrams "Theft" means that he is not willing to try making traditional things that have a comparable quality of a AI generated Art. Or he thinks that it is just not possible, he tries to eliminate the conflict by accusations, so that he can continue making he's art without any efforts of Improvements. But this method will not bring him any further nor it will make the Creator Artist Improve he's traditional creations.
