The rise of mass media (hollywood, netflix), pornography, the pill (and other forms of contraception), large expendable incomes, smart phones, pharmaceuticals - the world now is basically Huxley's + a bit of a Orwellian propaganda sprinkled on top to keep you in Huxley's world.
Maybe you could say that these are non-core aspects of the story, like the fact that in BNW they travel by rocket instead of jet, but I think they’re extremely central to the story.
These ideas didn’t come out of nowhere, many of them ( like the replacement of family life with communal life) were taken seriously by progressives of the day.
Huxley took the trends and novelties of the early 1930s and imagined what things would be like if they continued in that direction. Some trends continued, but others stalled out, and these trends are perhaps more interesting than the ones that continued.
Just consider the Facebook newsfeed. Do you think the false headlines, or the memes and reaction videos scattered throughout, have more of an effect on people's inaction to perceived injustice? People won't react any differently to a headline that claims one things or the other. That's Huxley's prediction right there.
