Studies predict that there will be more computer jobs, automation, robots and other technologies which will replace or enhance many current jobs. It is simply more cost effective to have a machine perform many tasks, and the newer technologies have other advantages like accuracy and safety. A job which might be dangerous for a human may be safely done by a robot.
Many jobs have already disappeared, or at least declined significantly. It is easy to see, even though the changes seem gradual. Cashier jobs and gas station attendant positions were replaced by automatic checkout and “pay at the pump,” leading to open worry and discussion by residents who were worried about losing their own jobs to technological changes.
Retail salespeople and cashiers are the most in danger of losing their livelihoods, and the United Way predicts that there is a 90% chance of those positions disappearing. Other jobs which could be on the chopping block include sales representatives, movers, janitors and health aides.
