I don't see any evidence of worker exploitation being caused in any even semi-direct way by AI integration. In the field of animation and VFX in particular, while I've never worked in that area myself, essentially everyone I've heard talk about it over decades has mentioned unbearable crunch being routine.

You mentioned earlier that AI makes labor weaker, but I really don't see a case for it. If anything, given how relatively cheap GenAI is, it should allow most anyone with artistic sensibilities and skill in the area who is willing to leverage it to go into business themselves with minimal capital. Why should GenAI give power to employers, especially if they're just paying another company for the AI models?
