Then probably I was wrong to omit that I have seen summary in Rust official guide. Which made me doubt it’s useless.
Though I also now suspect that I have much better memory than most people. (I mean, I always thought that it’s normal to remember near verbatim first few sentences of audiobook after listening to it twice and complain that you stuck on what was fifth. But maybe it’s not? Idk how to check)
Just a guess:
Introduction is useful to make a quick decision whether you want to read this article or not.
Summary is useful to review the key point, and increase the chance that you will remember them.
From the perspective of “how much I enjoy reading at the moment”, they are useless; possibly harmful.
