I don't think it will overhaul anything, but I'm excited to work as a hobbyist director at home using similar tools. Animatediff is a really cool start but its still too time consuming for me atm.
I always tell people if I couldn't work on computers in any capacity, my favorite thing I'd like to work on is directing movies. I've already played with animatediff and I can't wait to play with Sora. These new AI tools (especially FOSS ones) are an absolute boon for anyone without a major budget.
Those last two are just going to make llms harder to use and act dumber. Annoying but not the end of the world. I have no idea how disclosure can possibly be enforced though. There's just no realistic way to distinguish a reasonably good image generation and a photoshop job.
