I'm sure I'm going to offend a bunch of people with this, but my experience has been similar to yours, and it reminds me of something "Uncle" Bob Martin once mentioned: the number of software developers is roughly doubling every two years, which means that at any given time half of the developer population has less than two years experience. If you're an experienced dev, having a peer that enthusiastically suggests a bunch of plausible but subtly wrong things probably net-net slows you down and annoys you. If you're more junior, it's more like being shown a world of possibilities that opens your mind and seems much more useful. Anyway, I think the reason we see so much enthusiasm for LLM coding assistants right now is the overall skew of developers to being more junior. I'm sure these tools will eventually get better, at least I hope they do because there's going to be a whole lot of enthusiastically written but questionable code out there soon that will need to be fixed and there probably won't be enough human capacity to fix it all.
