Robot workers: Is coexistence possible?
For now, these machines are helping workers, not competing with them. But that could change as faster processors and improved sensors enhance robots' capabilities.
The robots are coming. Resistance is futile. From car factories to microprocessor plants to fulfillment warehouses, a single robot can now handle tasks that once took hundreds of man-hours to complete. This relentless march of automation is causing economic upheaval. As time goes on, companies will become more productive and more efficient, but the amount of human labor required will decrease, as will paychecks. The sentient worker will be reduced to a relic of a simpler age.
This is what we've been told, anyway.
To some economists, stubbornly high unemployment rates in the United States and Europe are at least partly attributable to the rise of machines.
"There's no question that in some high-profile industries, technology is displacing workers of all, or almost all, kinds," wrote Paul Krugman in The New York Times, adding that "many of the jobs being displaced are high-skill and high-wage."
Massachusetts Institute of Technology professor Erik Brynjolfsson says "Robots are becoming more capable and skilled, and people with the same sets of skills are not as much in demand." According to this view, robots aren't change agents. They're destroyers of worlds.
Yet the robot revolution doesn't have to cause panic. While robots can claim some technological superiority over humans, even the most sophisticated machines have limitations. Automation will inevitably displace jobs, but it's already bringing fresh economic opportunities as well.
A nation of farmers
The last two decades have shown how technology can create industries, even as it turns whole cities into has-beens. The ratio of jobs created to jobs eliminated by robots and where all the newfound wealth ultimately winds up are entirely dependent on how workers, businesses and policymakers prepare for this new era.
History is punctuated with scares about automation, with industries rising and falling based on changing technologies. Toward the end of the 18th century, 90% of the U.S. population was involved in farming. Farmers now make up 2% of the domestic workforce because of innovations such as tractors and grain combines.
More than any economy in the world, the U.S. has proven to be especially resilient in the face of massive technological change. Why should recent advances in robotics be any different?
It's too soon to write dirges for the humble human worker. In today's workplace, there are still things that robots just can't do. At Quiet Logistics, an order-fulfillment center for online retailers in Devens, Mass., 64 robots are used to move merchandise around the warehouse, but 330 humans are required to fold, package and ship the products. Why not have robots do the whole thing? "People are really good at picking up things," says Bruce Welty, Quiet Logistics' chief executive officer. "It's very difficult to get a robot to make the decisions required that a human makes to pick something out of a bin -- particularly if there are many different things in that bin."
Humans continue to have another advantage over robots: They remain a more flexible workforce. To handle this year's holiday shopping season, Amazon.com (AMZN) hired 50,000 part-time workers. While seasonal, part-time labor is not something you can necessarily build an economy on, it's worth noting that Amazon didn't buy more robots, because you can't hire a robot part-time (yet). What would additional robots do when demand receded? "Come January," says Jim Tompkins, a supply-chain consultant, "all that automation's going to be staring you in the face."
This is the state of the robotic arts today: a point where humans and robots share labor, with robots handling the simple and repetitive and humans taking care of the complex and dynamic. Some robotics designers and engineers would like this to be a blueprint for the future, where increased automation does not necessarily displace human beings.
How to share the wealth?
Rodney Brooks, a former MIT robotics professor, who is also the founder and chairman of robot maker Rethink Robotics, believes these machines are going to help workers, not compete with them. He points out that personal computers didn't get rid of office workers, they changed the jobs people did.
But robots are still in their relative infancy. As faster processors and improved sensors enhance robots' capabilities, it's highly possible that the peaceful coexistence between man and machine may evolve into something more competitive.
"In manufacturing, there's already a ton of innovation going on," says Brynjolfsson. Economists like him fear that as robots get smarter, the gross domestic product will expand at a healthy clip, but that positive data would mask reduced employment and lower wages. "Can GDP continue to grow? Of course it can," says MIT economist Frank Levy. "The question is: Can everyone benefit?"
Extrapolate this further and the role robots play in our economy and our lives begins to provoke fundamental questions about the nature of work. We have organized our economic system around the idea that income is derived from labor. But what happens when labor is not just transferred from one group of people to another (outsourcing) but to machines?
History has never shown that a life of idle hedonism brings out the best in human beings. We excel when we are creative and productive. To ensure that continues to be the case, we can't ignore or prevent the growth of automation, but we can bring our considerable talents to bear on determining what the future of work will look like.
For the U.S., that will require innovation and entrepreneurship, but also policies that foster those things -- such as an immigration policy that attracts and retains high-skilled newcomers who can help build job-creating industries, and a corporate tax rate that encourages investment in domestic opportunities and not offshore tax-haven chicanery.
Critically, more of the wealth created by productivity gains needs to be channeled into a stronger system of education and training.
If the robot threat proves overblown, and automation is not as transformative as is predicted or feared, then none of those efforts will have been in vain; they are answers not just to the threat of robots, but also to many other issues that challenge U.S. economic potential.
"Our economy has a lot of problems," says Northwestern University economist Robert Gordon. "If you're looking for new problems, it's not robots." It makes more sense to adapt to robots' taking our old jobs than to fight against it. Who knows? Once we figure out how to work with robots, we might even learn to love them.
