Education Could Shield Workers from AI
Not so long ago, computers were incapable of driving a car or translating a traveler’s question from English to Hindi.
Artificial intelligence changed all that.
Computers have advanced beyond the routine work they do so efficiently on assembly lines and in financial company back offices. Today, major advances in artificial intelligence, namely machine learning, have opened up a new pathway to expanding the tasks computers can do – and, potentially, the number of workers who may lose their jobs to progress over the next 20 years.
Machine learning works this way. A computer used to identify a cat by following explicit instructions telling it a cat has pointy ears, fur, and whiskers. Now, a computer can rapidly analyze and synthesize vast amounts of data to recognize a cat, based on millions of images labeled “cat” and “not-cat.” Eventually, the machine “learns” to see a cat.
But is this technological leap fundamentally different than past advances in terms of what it will mean for workers? And what about older workers, who arguably are more vulnerable to progress, because they have less time to see the payoff from updating their outmoded skills?
The answer, according to a third and final report in a series on technology’s impact on the labor market, is that advances in machine learning are likely to affect all workers – regardless of age – in the same way that computers have over the past 40 years.
And the dividing line, according to the Center for Retirement Research, will not be age. The dividing line will continue to be education: job options are expected to narrow for workers lacking a college degree or other specialized training, while jobs requiring these credentials will expand. …Learn More

Older Workers Ride Out Computer Age
The computer revolution, unleashed in the 1970s, has not stopped. Minicomputers replaced mainframes, and IBM introduced its personal computer. Then came the Internet, laptops, robots, iPhones, and increasingly intelligent software that can drive cars and discern music preferences.
Continual technological change has reshaped and regenerated the economy several times over, creating new types of jobs unimaginable a few years earlier. But the past four decades have also been tumultuous for the workers who were either replaced by machines or couldn’t keep up with the evolving demands of their jobs.
This is a pressing issue for the older workers who would benefit from working longer to improve their retirement finances. An erosion in their physical stamina or mental agility conceivably makes them more vulnerable to losing out to progress. And it can be difficult for people who have invested years in a job to train for and find new employment.
But a new study of labor force trends by the Center for Retirement Research finds this has not been the case. The computer age has had about the same impact on workers over age 55 as it has had on the labor force overall.
Two factors have proved essential to whether people – whatever their age – have had job security in this period of change: whether the work is routine and whether it requires a college education.
Since the 1970s, job options have narrowed for many workers who did not attend college, because computers have been especially good at rapidly and tirelessly performing the routine tasks this group’s work often entails. Examples are the computerized financial transactions that replaced back-office workers who entered the data manually and the robots inserted into assembly lines. The more routine a worker’s job, the more vulnerable he is to being replaced by a machine.
The upshot is that this segment of the labor force is shrinking: roughly a third of U.S. workers hold routine jobs currently, down from more than half in 1979. Nevertheless, the magnitude of this decline has been roughly the same for workers over 50 as for the labor force overall, according to the study, which was conducted for the Retirement and Disability Research Consortium.
In contrast, computerization has not affected the demand for non-routine work that is physical in nature, such as construction and food preparation. These jobs typically do not require a college education either, but it has been virtually impossible to program computers to do non-repetitive work. “The rules governing our innate abilities are a mystery,” and this has protected jobs that emphasize uniquely human abilities, the researchers said.Learn More

Workers, Machines and Constant Change
Anyone who drives on the nation’s toll roads has used a job-eliminating device: electronic tollgates.
Unemployment due to new technologies – and workers’ resistance to them – are as old as the industrial revolution. In the early 1900s, glassblowers were replaced by mechanized bottle makers. Today, autoworkers are no longer necessary to bolt car parts to carriages – robots do it with speed and precision. Toll takers are the latest disappearing breed.
Workers who lose their jobs to progress face painful transitions, and pessimists throughout history have warned about technologies increasingly rendering human effort obsolete. Indeed, jobs can seem to vanish overnight after an entire industry or occupation adopts a laborsaving machine, presenting displaced individuals with difficult choices. They must either invest in a new skill or move into a low-skill, lower-paying job.
But in the long arc of history, technology is continually creating new jobs to replace the old ones.
“The cycle of job destruction and creation has produced a labor force where, over the long run, workers have generally found jobs – albeit jobs that largely did not exist 100 years ago,” concludes the Center for Retirement Research in the first of three reports on technology’s impact on older workers for the Retirement and Disability Research Consortium.
The changing nature of work encourages new forms of growth by expanding the economic pie. For example, about a third of U.S. workers used to be on the farm before being largely replaced by agricultural machinery like combines and threshers, the report said. But during and after World War II, new technologies adopted by industry supplied manufacturing and office jobs to the farmers who had migrated to the cities to work. Wages rose and the economy grew rapidly during this period of unprecedented abundance.
Another way that technology helps the economy is by making goods cheaper to produce and buy, freeing up demand for other products. For example, Americans spend 15 percent of their budgets on food – less than half of what they spent in 1900 before farms became fully mechanized. More money for cell phones. …Learn More
