How about a smart toaster? It knows what kind of bread you feed it, toasts it just right and understands your feedback. This way, it will update a neural network that covers all types of bread it has ever seen and how you like them toasted.
See also the Sirius Cybernetics Corporation Nutri-Matic Drinks Dispenser, designed to work out precisely what drink someone wants through careful analysis of their taste bud patterns and neurological signals before invariably producing a liquid which is almost, but not quite, entirely unlike tea.
And once the toast is ready, the machine pukes it out for you to enjoy. It’s sort of like the way birds feeding their young. The toaster should also make a relevant sound when that happens to max out everyone’s unsettle-o-meter. If you like, you can even record your own authentic sound on the next Saturday morning.
