I read it when I was a child, but I didn't quite understand it back then. I was glad to reread it and re-evaluate it. Each book raises some serious issue, some interesting question... And the answer turns out to be unexpected. Overall, I recommend it.
However, the ending of the last story is a bit weak; this P. acted too foolishly!
"The Hereditary" - R. Heinlein
A short story, but quite entertaining. Although he tried to convey social problems to the reader in many ways, I couldn't shake the feeling that he was a bit naive. The characters don't behave selfishly enough! But overall, it's good.
"Harry Potter and the Methods of Rationality" - E. Yudkowsky
Excerpts from this fanfiction always seemed amusing to me, but not interesting enough or natural enough to make me want to read the whole book. But friends and acquaintances kept recommending it, and I gave in.
And I didn't regret my decision. Honestly, I think that this is exactly how the story of Harry Potter should have looked from the beginning. In this version, it has become not only smarter. There is more genuine intrigue here. There are more emotions. There is more logic. And yes, there is the so-called "geeky" humor, and within the book, it really looks funny and not artificial. There are all sorts of references. It was a great read.
The downside is that it is still a fanfiction (it would be great if this book were based on a unique world with unique characters, with all its other advantages. But as it is, it seems to diminish the fact that not all of the author's imagination comes from his own head). And somewhat the author's worldview made the book less logical in some places where it could have been. He is too much of a humanist. It's a bit strange to be "too much of a humanist," but if anyone has read it, or will read it to the end, they will understand. And yet, all of this is not enough to stop you from reading the book.
