This post about neural networks is from the "Math" book: https://news.ycombinator.com/item?id=45434678.
I'd vote for flagging this submission. It's just AI slop.

As much as I would like to believe that, there are too many red flags at this point and you have given little indication that it's true. If you really are an expert in all the fields of your little books, it should be easy for you to provide references/credentials?
No, that's not gatekeeping, as in this day and age, those things become more and more important to be able to separate the sea of slop from the real deal.
Although I've also been thinking about the overall role of effort in products, art, or any output really. Necessary effort to produce something is / was at least some indicator of quality that means that the author spent a certain amount of time with the material, and probably didn't want to release something bad if it meant they had to put a certain threshold of effort in anyways. With that gone, of course some people are gonna get their productivity enhanced and use this tool to make even better things, more often. But having to expend even more engery as a consumer to find out whether something is worth it is incredibly hard.
There is no obvious authorship attached to this "Little book" which is a tell-tale sign since anybody investing time into actually writing such a book would surely like to claim authorship.
