There is scarcely a shampoo or lotion for sale that does not promise an extraordinary result owing to essence of coconut, or rosemary extracts, or another botanical. As devotees of technology we are, if anything, more susceptible to the supposed degree of difference afforded by some ingenious proprietary innovation, like the “air” in Nike’s sports shoes, triple reverse osmosis in some brands of water, or the gold-plating of audio component cables.
