It's more likely that you're still going to be filming/editing/animating but will have an AI layer on top that produces extra effects or generates pieces of a scene. Think "green screen plus", vs fully AI entertainment.
People will over-hype this tech like they did with voice and driverless cars but don't let it scare you. Everything is possible, but it's like a person from the 1920's telling everyone the internet will be a thing. Yes it's correct, but also irrelevant at the same time. You already have AI assisted software being used in your industry. Just expect more of that and learn how to use the tools.
