I've tried a lot of scenarios and languages with various LLMs. The biggest takeaway I have is that AI can get you started on something or help you solve some issues. I've generally found that anything beyond a block or two of code becomes useless. The more it generates the more weirdness starts popping up, or it outright hallucinates.

For example, today I used an LLM to help me tighten up an incredibly verbose bit of code. Today was just not my day and I knew there was a cleaner way of doing it, but it just wasn't coming to me. A quick "make this cleaner: " and I was back to the rest of the code.

This is what LLMs are currently good for. They are just another tool like tab completion or code linting
