I use these tools a lot, and one thing that has stood out to me is that they LOVE to write code. A lot of it. And they're not super great at extracting the reusable parts. They also love to over-engineer things.

I've taken great pains to get by with as little code as possible, because the more code you have, the harder it is to change (obviously). And while there are absolutely instances in which I'm not super invested in a piece of code's ability to be changed, there are definitely instances in which I am.

Yea, by my less is more logic its sometimes also difficult to do. With that approach people try to become clever and write shorter code thats unmaintainable due to mental gymnastics other people have to go through when reading it. What LLMs are doing is probably going for some kind of overengineered "best practice" solution. I personally only use them for simple Laravel CRUD apps and they are admittedly pretty good at that.
