Sounds like we are in agreement: LLMs are a great help to an already good engineer.

But also to the original Simon's point that using LLM does not a good engineer make — how we make one is still on us with 10+ years (I've got "only" 20) of experience to figure out now that LLMs are here!

Implicit definition of a good engineer is the one who chooses the right balance between effort, complexity, performance to build a working software system for a business need that can be evolved according to (unforeseen!) future business needs at reasonable cost.
