Thanks to the developments in technology, we are now able to do many things we couldn’t do before: we can travel in space, we can measure the temperature of lava while it’s still bubbling in the volcano, and we can perform surgery that is so delicate and minute that the cut is only 4mm long. But the reverse is also true; many people are at risk of losing their jobs because technical innovations have taken them over. Here is a list of jobs that have been usurped by technology:
Interestingly, agriculture is the industry that works closest with nature, yet so many of it is mechanized now that one person can single- handedly sow and reap acres upon acres of grain, which used to be the effort of an entire village. There are machines that will disperse the fertile wheat grains in the field at an even, optimum distance for growth. There is a machine for spraying insecticides. There is a machine to reap the wheat and there is an additional machine to tie them in bundles while someone at the back will collect them and put them in gurney sacks to be sold.
Where earlier there would be dozens of coordinators in an office, each responsible for one or two aspects of a business, today there is supply and chain management software that had whistled that position down to one person who can sit behind a computer and coordinate several processes and outcomes at the same time.
Supply chain software cuts down on time and manpower, saving the company money on both fronts and most companies use it to increase efficiency. Since a computer can arrange and coordinate much more faster and more accurately than a human can, there is no hope for humans trying to win their jobs back.
Construction is one of the few fields which still hire many people, but only because of its high turnover. Most aspects of the job are carried out with the aid of machines. Backhoes and caterpillars dig into soil in half a day what would normally take the effort of ten men over a couple of days. Cement is no longer mixed manually; there is a mechanical mixer for that. Even painting is done with spray cans that have a smoother finish than manual painting. While machines have not been able to completely take over human positions in construction work, it has put a limit on the number of men or women needed at a particular job as only one or two is actually needed to operate one.
