In the near future, technology will eliminate many jobs and there are suggestions that this will happen at a surprisingly fast pace. As companies such as Google continue to develop driverless cars, for example, professional drivers may soon disappear.
Likewise Amazon is starting to build retail stores of the future, where everything necessary to purchase the goods will be taken care of by automatic sensors. Thus the staff headcount will be reduced. For those who prefer shopping online, orders will be delivered by drones instead of human couriers.
