People keep talking about using LLMs for writing code, and they might be useful for that, but I've found them much more useful for explaining human-written code than anything else, especially in languages/frameworks outside my core competency. E.g. "why does this (random code in a framework I haven't used much) code cause this error?" About 50% of the time I get a helpful response straight away that saves me trawling through Stack Overflow and random blog posts. About 25% of the time the response is at least partially wrong, but it still helps me get on the right track. 25% of the time the LLM has no idea and won't admit it so I end up wasting a small amount of time going round in circles, but overall it's a significant productivity boost when I'm working on unfamiliar code.
