Bokanovsky's Process involves splitting a single embryo into anywhere from eight to 96 identical embryos, each of which will grow into an identical human being.
When one of the students asks what the advantage of this is, the Director tells him that it creates unprecedented social stability:
“Ninety-six identical twins working ninety-six identical machines!” The voice was almost tremulous with enthusiasm. “You really know where you are. For the first time in history.” He quoted the planetary motto. “Community, Identity, Stability.”

People are created to be happy in whatever caste they end up. Further, this method removes traditional parents from the mix and all the uncertainty that introduces into the social order. People have no parent but the state laboratory. People in this world are blind to how dehumanizing this process might be, but Huxley expects the reader to understand the satire.
