The philosophy of over-population, over-organisation, and propaganda in totalitarian and capitalist societies will always be a debatable. Huxley does a decent job in trying to explain how scientific and technological advancements will/have influenced these topics.

Unfortunately, the short coming of the text resides in the fact Huxley did not predict the development of the internet. We are lucky, despite the NSA etc, that the internet has extended our civil liberties, rather than degraded. However, as the key message of the book continually enforces, concentration of power in few hands can destroy the power of the technology to extend our liberties.

In summary, the first half and last two chapters of the book present ideas that are as salient today as in the 1960s. However, Huxley's ideas about psychology, biology and psychiatry in the remaining chapters are well and truly dated.
