This probably doesn't give them enough credit. If you can feed an LLM a list of crash dumps it can do a remarkable job producing both analyses and fixes. And I don't mean just for super obvious crashes. I was most impressed with a deadlock where numerous engineers and tried and failed to understand exactly how to fix it.

LLMs are good where there is a lot of detail but the answer to be found is simple.

This is sort of the opposite of vibe coding, but LLMs are OK at that too.
