The World State uses various types of technology to control people’s lives long before they are “decanted,” or born. From an advanced understanding of eugenics to hypnopædia to Pavlovian-style conditioning, infants’ lives are determined by technology before they have any awareness of what is around them. Furthermore, technologically advanced means of entertainment, travel, and transportation surround people in their day-to-day lives, and robust anti-aging technology in the medical realm allows people to look and feel young (and thus focus on living in the present) even as they grow older.

Controllers like Mustapha consider technology critical to society because it enables control of the people, which in turn enables a peaceful, happy, orderly way of life. Without advanced technology and scientific understanding, the World State would not be able to exist. Because of how ubiquitous technology is in Brave New World, this manifests into a theme cautioning against unrestrained technology for the sake of progress and control.
