Much like 1984 by Orwell it doesn't go far enough, both assume there will be humans in control that aren't as strongly or more under the influence of hyper-real superstition, and actively use coercive technologies to keep other people in line without being fully subject to them. It's quite the happy path compared to contemporary 'Reddit occupied government'-style of political governance.
One should also note that Aldous Huxley (like his brother) was a eugenicist, and people being distracted from performing their eugenic duties is a fear that echoes in his supposed dystopies. See e.g. https://archive.vanityfair.com/article/1927/10/a-note-on-eug...:
"[D]eficients are not only preserved: they are also permitted to multiply their kind."
IIRC Huxley became rather sceptical in his later works regarding "eugenics" or in general "scientific dictatorship" as a solution to the social problems of humanity.
I may have to re-read his work "Ends and Means" sometime later, but I'm quite sure that calling him an "eugenicist" is too easy.
EDIT: fixed typo
He supported Muller's germinal choice scheme, according to In the Name of Eugenics, p. 262-263: http://pinguet.free.fr/kevles1985.pdf
What sources is it you remember?
And about 30 years later his book "Brave New World revisited" where he stated that "Brave New World" appeared much faster then he expected.
