Items created for efficiency have now become so detailed they may negate their original functions.

The modern washing machine has a dozen or more cycles that no one has ever used. The “baby cycle”, for example, aimed, presumably, at parents too lazy to wash their babies in the bath. Or, quoting now from a variety of machines, the “duvet”, “sports”, “bed and bath”, “reduced creases”, “allergy” and “freshen up” cycles. As in “I’m just going to hop in the washing machine and freshen up.” (Yes, I realise it freshens up clothes, not people, but still I bet no one has ever used it non-ironically.)
