I've always preferred tactile/mechanical controls (buttons, knobs, sliders) to the touch screens we have today. And I always trust mechanical systems over fly-by-wire systems. For example, I'm very uncomfortable with things like the Tesla's slide-out door handles, electronic locks in hotel room doors, touch buttons in elevators and GPS navigation systems in aircraft.

Smart tends to mean complex, and complex usually means more things to fail. Some things only need shafts, pulleys and gearwheels -- there is no need to bring a microprocessor into the picture...
