Its impossible to hand roll code at the same rate as an LLM. Which means that if you don't use them, you better have a good explanation for your manager as to why you're clearing far fewer features/tickets relative to your colleagues.
You can try the "But my quality is higher/defect rate is lower", but that gap is shrinking, and it doesnt seem like game studios even care about that anyway.
We all still have the skills to write code, its just that the people who pay us don't actually care about human written code, they care about getting the game/software written as fast as possible.
