To me that makes coding LLMs the new Excel.

I mean that in the sense that Excel is the tool that non developers could take the farthest to meet their needs without actually becoming a full time developer. But then to take it past that point a professional developer needs to step in.

I imagine non devs vibe coding their way to solutions far more complex than Excel can handle. But once they get past the greenfield vibe coding stage they will need a pro to maintain it, scale it, secure it, operationalize it, etc.
