LLM has been hollowing out the mid and lower end of engineering. But has not eroded highest end. Otherwise all the LLM companies wouldn’t pay for talent, they’d just use their own LLM.

The talent isn't used for writing code anymore though. They're used for directing, which an LLM isn't very good at since it has limited real world experience, interacting with other humans, and goals.

OpenAI has said they're slowing down hiring drastically because their models are making them that much more productive. Codex itself is being built by Codex. Same with Claude Code.
