Imagine a world where a pilot would have to fly an over 500-ton, 4-engined Airbus A380 with virtually no flight instruments, only a primitive joystick and maybe a headlight for night landings. Imagine a captain navigating through a coral reef full of underwater ridges, or maneuvering beneath the polar ice sheet, all while commanding a submarine without sonar and basic instruments. Imagine a construction equipment operator required to excavate a 400m long, 3m deep ditch - although the excavator they are manning only has a number of peepholes in solid metal cabin walls instead of proper windows.
