Once born, the children are all conditioned - using electric prods in the show and hypnopedia in the book - to stick to their designation. The five castes are Alpha, Beta, Gamma, Delta, and Epsilon Alphas and Betas are designated the smartest and most privileged, while the lower castes are cloned and given undesirable jobs. Human beings no longer reproduce, and each fetus is created in a lab and designated as a particular caste. In Huxley's novel, Lenina and Bernard's society - a so-called utopia that's actually a dystopia - is called The World State, and it's similar to Brave New World's New London. While the show still focuses on their evolving relationships, there's quite a few differences between the Brave New World show and the book. Based on Aldous Huxley's 1932 dystopian novel of the same name, Brave New World puts a modern spin on the tale of Bernard (Harry Lloyd), Lenina (Jessica Brown Findlay), and John the Savage (Alden Ehrenreich). Though Peacock's Brave New World adaptation engages with questions of individuality, agency, and the dangers of technology, at the core of the story is also a love triangle.
