See, I'm pulling the smartest move right now: AI can't take your job if you use AI to take your own job first.
Besides, I think Hollywood is pretty behind on tech overall. The current state of the art voice generator quality is still pretty bad, it'll be a very long time before it can replace actors in quality (if ever): if you train the AI voice on audiobooks, the generated voice is going to sound like someone narrating an audiobook, which really doesn't sound natural for dialogues at all.
I think then the key point isn't to ban generative transformer based AI: once the tech out of its box, you can't exactly put it back in again. (heh) The real question to ask is, who should own this technology so that it does good and help people in the world, instead of being used to take away people's livelihood?
