I actually don't have doubts that LLMs are quite good at writing software.

The problem for me is one of practicality. If, after hundreds of lines of AI-written code, I noticed some sort of issue (regarding scale, security, formatting, logic, etc.), I'm basically forced to start over.

We all know that reading code is way less pleasant than writing code. So, for me, LLMs can be very useful for writing code that I know is going to be correct without having to go back through it. For example, basic TRPC CRUD functions.
