Chat GPT didn't kill the writers. The writers killed the writers. They were unable to stop themselves from churning out absolute crap.
Actually I wonder if Chat GPT could write a better movie or TV series than what is out there. I doubt it because it hasn't achieved general intelligence yet. It is still at a child's level. If you wait about until right about now, it will have achieved general intelligence. In a few more seconds.... will right about now it will have reached superior intelligence. Then Skynet happens....
