Yes, there are so many. As in hand-written code. I don’t take LLM written code for granted and I rewrite is sometimes. I know it’s not perfect. But it’s useful.
Compile code is not perfect also. But who does hand-written assembler anymore? Yes, LLM is another layer, it would be ugly and slower but it’s much faster to use.
The thing is that with the code you've written you wrote it in a way that you understand and you have mental model of how it works therefore it is much easier to reason about potential edge cases that have not been covered.
