Unemployment from Robotics, Artificial Intelligence and Computers - Will Robots and Machines steal our Jobs?

Could Advancing Job Automation Technology Cause Structural Unemployment?

The unemployment situation is looking increasingly dismal. Is it possible that there’s something going on that no one wants to acknowledge?

There can be little doubt that computers, robotic technologies and other forms of job automation have been getting far more capable and that as this trend continues, more workers are certain to be displaced in the relatively near future. Most economists dismiss any concern that this might lead to long-term structural unemployment. At the risk of being labeled a “neo-Luddite,” I’d like to explore this issue a little further.

I think I can make a fairly strong argument that a very large percentage of jobs are, on some level, essentially routine and repetitive in nature. In other words, the job can be broken down into a discrete set of tasks that tend to get repeated on a regular basis. It seems likely that, as both hardware and software continue to advance, a large fraction of these job types are ultimately going to be susceptible to machine or software automation.

I’m not talking about far fetched science fiction-level technology here: this is really a simple extrapolation of the expert systems and specialized algorithms that can currently land jet airplanes, trade autonomously on Wall Street, or beat nearly any human being at a game of chess. As technology progresses, I think there is little doubt that these systems will begin to match or exceed the capability of human workers in many routine job categories–and this includes a lot of workers with college degrees or other significant training. Many workers will also be increasingly threatened by the continuing trend toward self-service technologies that push tasks onto consumers.

One of the most extreme historical examples of technologically induced job losses is, of course, the mechanization of agriculture. In the late 1800s, about three quarters of workers in the U.S. were employed in agriculture. Today, the number is around 2-3%. Advancing technology irreversibly eliminated millions of jobs.

Obviously, when agriculture mechanized, we did not end up with long-term structural unemployment. Workers were absorbed by other industries, and average wages and overall prosperity increased dramatically. The historical experience with agriculture is, in fact, an excellent illustration of the so-called “Luddite fallacy.” This is the idea–and I think it is generally accepted by economists–that technological progress will never lead to massive, long-term unemployment.

The reasoning behind the Luddite fallacy goes roughly like this: As labor-saving technologies improve, some workers lose their jobs in the short run, but production also becomes more efficient. That leads to lower prices for the goods and services produced, and that, in turn, leaves consumers with more money to spend on other things. When they do so, demand increases across nearly all industries–and that means more jobs. That seems to be exactly what happened with agriculture: food prices fell as efficiency increased, and then consumers went out and spent their extra money elsewhere, driving increased employment in the manufacturing and service sectors.

The question we have to ask is whether or not that same scenario is likely to play out again. The problem is that this time we are not talking about a single industry being automated: these technologies are going to penetrate across the board. When agriculture mechanized, there were clearly other labor intensive sectors capable of absorbing the workers. There’s little evidence to suggest that’s going to be the case this time around.

It seems to me that, as automation penetrates nearly everywhere, there must come a “tipping point,” beyond which the overall economy is simply not labor intensive enough to continue absorbing workers who lose their jobs due to automation (or globalization). Beyond this point, businesses will be able to ramp up production primarily by employing machines and software–and structural unemployment then becomes inevitable.

If we reach that point, then I think we also have a serious problem with consumer demand. If automation is relentless, then the basic mechanism that gets purchasing power into the hands of consumers begins to break down. As a thought experiment, imagine a fully automated economy. Virtually no one would have a job (or an income); machines would do everything. So where would consumption come from? If we’re still considering a market (rather than a planned) economy, why would production continue if there weren’t any viable consumers to purchase the output? Long before we reached that extreme point of full automation, it seems pretty clear that mass-market business models would become unsustainable.

One of the things that concerns me the most about this scenario is the potential influence of consumer psychology. If at some point in the future consumers look out the window and see a landscape where jobs are relentlessly getting automated away, and if it appears that getting additional education or training provides little protection, there’s likely to be a significant negative impact on consumer sentiment and discretionary spending. If we someday get into a reinforcing cycle driven by fear of automation, a very dark scenario could ensue. It’s difficult to see how traditional policies like stimulus spending or tax cuts would be effective because they wouldn’t address consumers’ concerns about long-term income continuity.

Most economists will likely object to my arguments here as speculative and lacking in objective data. I think that if you look at issues like stagnating or declining wages for average workers, growing income inequality, increasing productivity, and consumption supported by debt rather than income, you can certainly find evidence that generally suggests we might be approaching that “tipping point” where structural unemployment is going to become a problem. However, it seems unlikely that an econometric analysis of past data is going offer clear support for this theory–and if it ever does, it will be very late in the game.

I wonder about the wisdom of the extreme emphasis on quantitative data analysis that seems to characterize economics. Should we really steer the ship exclusively by focusing our telescope on the wake? There might be an iceberg ahead.

  1. I can imagine, in a nearly fully automated economy, a counter-culture demand would develop for "human-made" products, analogous to organic food industry we see today -- where consumers are willing to pay a premium for goods and services that do not use automation methods.

  2. You explore a topic that no one in the media or our government wish to explore. We have ATMs/online banking which are reducing the need for tellers ...and now even self checkouts which are taking the jobs of cashiers. It is a bleak future.

  6. Even when smart people are told to prepare an article or a short story or just a simple overview of any kind, most of students tend to apply for some writing service assistance. Such sort of occupation requires serious brains as well as critical cogitation in a readable and structured form. Reflections when to pay someone to write your paper on dependency on computers with http://papersmart.net/pay-for-papers.html made by our cheap writers are worthy of a deep research on a pointed theme. Ask for our help you know there must be someone to help you in.
