I've found that LLM helps me to write good code. It essentially works like a colleague who can review my code. It spotted many issues which I wouldn't spotted before. It also helps to free me from some mundane work.

In the end, my immediate productivity with LLM is a lot lower than before. But I assume that quality is a bit higher, at least in the long run, because issues fixed early saves a lot of time later.

I guess I don't use LLMs like a lot of other people. In fact I continue to write most code myself and I just use LLM to aid me or to generate something that's very similar to existing entity and just requires careful copy&paste&replace. My only fear is that this approach to work is not very popular and I might be asked one day to switch to wipe code, which I don't enjoy at all.
