You have to think of the LLMs as more of a better search engine than something that can actually write code for you. I use phind for writing obscure regexes, or shell syntax, but I always verify the answer. I've been very pleased with the results. I think anyone disappointed with it is setting the bar too high and won't be fully satisfied until LLMs can effectively replace a Sr dev (which, let's be real, is only going to happen once we reach AGI)
