If an LLM can get you 90% of the way there, you need fewer engineers. But the engineer you need probably needs to be a senior engineer who went through the pain of learning all of the details and can function without AI. If all juniors are using AI, or even worse, no juniors are ever hired, I'm not sure how we can produce those seniors at the scale we currently do. Which isn't even that large a scale.
