I have thoroughly enjoyed the author's quantum country (https://quantum.country https://quantum.country) and can definitely vouch for that essay's methods of improving cognition. 6 months later I can still recall quantum computation, which was a black box to me earlier. However, I'm not sure I fully agree with with this essay, specifically the definition of what it means for a book to "work". Is it necessary to be able to recall a book or a talk? I mean, it is good if you can, but is it a failure if you don't? Perhaps it isn't the fault of the medium. It may be the way our brains are structured. Maybe reading a book changes something subtly, not enough for recall, but a change nevertheless. Like training a neural net with one training example. I know that when I dig out a book that I have put aside several years ago, it seems much more approachable. I think that reading a book increases your _capacity to receive_, and the more you read similar stuff (or the same thing over again), the more you are able to absorb. There comes a tipping point where you are able to see connections to other things you have read. I approach books and articles like I approach music: I don't expect to recall much. If I want to recall it, I expect to revisit the material. Either way, the hours spent on it have not been fruitless.
