I'm rereading "A Brave New World" by Aldous Huxley, and aside from the class systems, test tube babies, genetic engineering, pill popping, and other things he was dead on with, here is a passage predicting something I don't think many envisioned:
And around her waist she wore a silver-mounted green morocco-surrogate cartridge belt, bulging (for Lenina was not a freemartin) with the regulation supply of contraceptives.
Yup. He predicted that Lisa "Left Eye" Lopes and the rest of TLC would wear condom accessories as part of their wardrobe. Bravo, Aldous. That is probably something he threw in there to exaggerate for effect, but yup, modern society is that stupid.
