The lesson to learn is that these are "large-language models." That means it can regurgitate what someone else has done before textually, but not actually create something novel. So it's fine if someone on the internet has posted or talked about a quick UI in whatever particular toolkit you're using to analyze data. But it'll throw out BS if you ask for something brand new. I suspect a lot of AI users are web developers who write a lot of repetitive rote boilerplate, and that's the kind of thing these LLMs really thrive with.
