I think it depends on how much control you feel you want to have over your output. AI tools are decent at rendering video, but for those that want full control over the process, I feel like it's going to be a long way to go. If AI is able to generate the full source files to allow things to be modified, then I would 100% agree with you that it's going to be a new age for artists. If you're dealing with raw generated video, or even a frame by frame rendered image, your control is much more limited than if you could shape and customize your models. For most, this is probably fine, but for those that want fine-grained control, there is a far path to go in order to get to that point.
