Film/video editing isn't exactly known as the industry where everybody loves their job and doesn't want to kill themselves.
I made a twitter thread[1] with weird metal cybertrucks using Midjourney a couple days ago. I personally enjoyed the process and do not have the talent nor the time to do that without generative AI. There are people who do have that talent, but honestly I doubt anyone else would've put in the time.
I think you might have it a little backwards. For most people, the fun part is "making a movie", not "watching hundreds and hundreds of hours of footage picking between 10 different shots". That's the drudgery, and that's the part generative AI can eliminate.
