There are many ways to answer this question. A little background might be helpful. By the time Huxley wrote the work, he had already been known as a satirist. Moreover, H. G. Well came out with a book called, Men Like Gods, which had a view of the future that was very positive. So, Huxley's work is a satire of Wells' utopian society.
With that said, there are several ways in which Huxley uses satire to speak of the future. Perhaps the greatest way was through his acknowledgement of the great advancements that had been made during his time. In his context, the industrial revolution did wonders to the world; things were being made quicker, cheaper, and some would argue even better. In this fast paced society, people saw a bright future. However, Huxley took all of this and made it the very thing that subjugated people.
People did not control technology. Technology controlled them in his novel through pleasure and consumption. There were little real choices for people and the idea of the individual was done away with. For instance, one of the quotes of the book was, "spending is better than mending."
From this perspective, we can say that Huxley was prophetic in a sense. Today we live in a consumeristic society and people's decisions are based on consumption. People are enslaved to shopping and for this reason, there is little left of the individual.
