I've been coding with LLMs for less than a year. As I mentioned to someone in email a few days ago: In the first half, when an LLM solved a problem differently from me, I would probe why and more often than not overrule and instruct it to do it my way.

Now it's reversed. More often than not its method is better than mine (e.g. leveraging a better function/library than I would have).

In general, it's writing idiomatic mode much more often. It's been many months since I had to correct it and tell it to be idiomatic.
