Eeeh, I spend less time writing code, but way more time reviewing and correcting it. I'm not sure I come ahead overall, but it does make development less boilerplaty and more high level, which leads to code that otherwise wouldn't have been written.

I wonder if you observe this when you use it in a domain you know well versus a domain you know less well.

I think LLM assistants help you become functional across a more broad context -- and completely agree that testing and reviewing becomes much, much more important.

E.g - a front end dev optimizing database queries, but also being given nonsensical query parameters that don't exist.
