Huxley predicted more than just rocketry and helicopters; from Brave New World
"“That’s a charming little group,” he said, pointing.
In a little grassy bay between tall clumps of Mediterranean heather, two children, a little boy of about seven and a little girl who might have been a year older, were playing, very gravely and with all the focussed attention of scientists intent on a labour of discovery, a rudimentary sexual game.
“Charming, charming!” the D.H.C. repeated sentimentally.
“Charming,” the boys politely agreed. But their smile was rather patronizing. They had put aside similar childish amusements too recently to be able to watch them now without a touch of contempt. Charming? but it was just a pair of kids fooling about; that was all. Just kids.
“I always think,” the Director was continuing in the same rather maudlin tone, when he was interrupted by a loud boo-hooing.
From a neighbouring shrubbery emerged a nurse, leading by the hand a small boy, who howled as he went. An anxious-looking little girl trotted at her heels.
“What’s the matter?” asked the Director.
The nurse shrugged her shoulders. “Nothing much,” she answered. “It’s just that this little boy seems rather reluctant to join in the ordinary erotic play. I’d noticed it once or twice before. And now again to-day. He started yelling just now …”
“Honestly,” put in the anxious-looking little girl, “I didn’t mean to hurt him or anything. Honestly.”
“Of course you didn’t, dear,” said the nurse reassuringly. “And so,” she went on, turning back to the Director, “I’m taking him in to see the Assistant Superintendent of Psychology. Just to see if anything’s at all abnormal.”
“Quite right,” said the Director. “Take him in. You stay here, little girl,” he added, as the nurse moved away with her still howling charge. “What’s your name?”
“And a very good name too,” said the Director. "Run away now and see if you can find some other little boy to play with."
The child scampered off into the bushes and was lost to sight.
“Exquisite little creature!” said the Director, looking after her. Then, turning to his students, “What I’m going to tell you now,” he said, "may sound incredible. But then, when you’re not accustomed to history, most facts about the past do sound incredible."
He let out the amazing truth. For a very long period before the time of Our Ford, and even for some generations afterwards, erotic play between children had been regarded as abnormal (there was a roar of laughter); and not only abnormal, actually immoral (no!): and had therefore been rigorously suppressed.
A look of astonished incredulity appeared on the faces of his listeners. Poor little kids not allowed to amuse themselves? They could not believe it.
“Even adolescents,” the D.H.C. was saying, “even adolescents like yourselves …”
“Barring a little surreptitious auto-erotism and homosexuality–absolutely nothing.”
“In most cases, till they were over twenty years old.”
“Twenty years old?” echoed the students in a chorus of loud disbelief.
“Twenty,” the Director repeated. “I told you that you’d find it incredible.”
