> LLMs, in my opinion, are on average better at writing copy than humans.

I disagree here.

But what I found LLMs really useful for is summarizing topics like: "Suppose I want to do XYZ, which steps should I take?" or "I want to write about ABC, how would you structure the article?"

The content is not very good if you look at it in detail, but LLMs provide good overviews and gave me ideas on parts of a topic I overlooked.

More librarian than search engine. I cannot copy and paste and rely on the results but I can rely on that they point me in a good direction.
