I'm not sure how you came away with that impression. Three out of three reviewers say they overall enjoyed the book. The complaints fall mostly into four buckets:

- "I wish the book was simpler" (Jesse)

- "I wish the book was more advanced" (Murat)

- "I wish software engineering was more advanced" (Andrew)

- "I didn't understand the arguments the author made for why studying single-server exponential response time systems helps with drawing conclusions for time-sharing, heavy-tailed response time systems" (Jesse)

None of these paint the book in a bad colour, as far as I can tell. They say more about the reader's expectations than the book itself.

Sure. But I'm trying to connect what you said:

> you'll come out with superpowers you didn't have before.

with the impressions from the reviewers.

I don't think they got super powers from the book. In fact their outcomes mirrors my own outcomes when going deep into some math topics and then bringing them to work.
