I have been saying this about llms for a while - if you know what you want, how to ask for it, and what the correct output will look like, LLMs are fantastic (at least Claude Sonnet is). And I mean that seriously, they are a highly effective tool for productive development for senior developers.

I use it to produce whole classes, large sql queries, terraform scripts, etc etc. I then look over that output, iterate on it, adjust it to my needs. It's never exactly right at first, but that's fine - neither is code I write from scratch. It's still a massive time saver.
