When will robots replace workers?

By Betty on June 25 2017

The falling cost of industrial robots will allow manufacturers to use them to replace more factory workers over the next decade while lowering labor costs, according to new research.

Robots now perform roughly 10 percent of manufacturing tasks that can be done by machines, according to the Boston Consulting Group. The management consulting firm projected that to rise to about 25 percent of such "automatable" tasks by 2025.

In turn, labor costs stand to drop by 16 percent on average globally over that time, according to the research.

The shift will mean an increasing demand for skilled workers who can operate the machines, said Hal Sirkin, a senior partner at Boston Consulting.

Factory workers "will be higher paid but there will be fewer of them," Sirkin said.

The research found a tipping point for installing robots: Companies tend to start thinking about replacing workers when the costs of owning and operating a system come at a 15 percent discount to employing a human counterpart.

For example, in the U.S. automotive industry, which is predicted to be one of the more aggressive adopters of robots, a spot-welding machine costs $8 an hour versus $25 an hour for a worker.

Three-fourths of robot installations over the next decade are expected to be concentrated in four areas: transportation equipment, including the automotive sector; computer and electronic products; electrical equipment and machinery.

Adoption is forecast to be slower in industries in which tasks are more difficult to automate or labor costs are low, such as food products or fabricated metal.

Certain countries also are expected to be more brisk adopters. China, the United States, Japan, Germany and South Korea now account for about 80 percent of robot purchases and are expected to maintain that share over the next decade.
