Take my washing machine, for example. It has 16 settings, of which I have only ever used 3: 40', sports shoes, and a hot one for towels and bedding. I have no idea what the others are for and it’s never occurred to me to seek out their untapped use. So programme 4 (delicates) is my go-to place on the dial – probably has an imprint there by now.
The dishwasher – same story!
What technology do you ignore?
