I agree with your take, and I personally used Claude and ChatGPT to learn better/hone some skills while interviewing to land a new job. And they also help me get unstucked when doing small home fixes, because it's a custom-tailored answer to my current doubt/issue that a normal web search would make much more complicated to answer (I had to know more context about it). But still, they get things wrong and can lead you astray even if you know the topic.
