If AI is at the point where it is exactly as capable of your average junior 3D professional in 10 years, it will probably have automated a ton (double digit percentage?) of current jobs such that nothing is safe. There's a lot of complexity, it's fairly long time horizon, it's very visually detailed, it's creative and subjective, and there's not a lot of easily accessible high quality training data.

It's like 2D art with more complexity and less training data. Non-AI 2D art and animation tools haven't been made irrelevant yet, and don't look like they will be soon.
