In Brave New World Huxley predicted some things about the modern life. One thing he predicted was that babies could be produced in a lab and be genetically engineered. In modern time babies aren't produced like this but scientists have ways of making babies with chosen or desirable qualities. Although this is frowned upon because of ethical issues. It's not natural to choose how you would like your baby to look like
Also in Brave New World the world is dependent on technology much like our world today. In BNW everything relies on technology such as predetermining lifestyle like appearance and attitude. Now in our world today technology isn't used to determine our lives but help us function better. We use it for transportation, medical advancements and other things.
In Brave New World children would engage in erotic play, they would act sexual at a young age and this was seen as normal. If this was one of Huxley's predictions for the future he's wrong. If this occurred today it would be seen as sick and disgusting. It would be wrong and children are associated with innocence and sweetness because they don't know of the bad in the world yet. They also don't know anything about erotic play like the children in Brave New World.
