This year is the 150th anniversary of the creation of the periodic chart of the elements first published in 1869 by the Russian scientist Mendeleev. For someone who is 75, that’s effectively two lifetimes, so it doesn’t seem so long ago. And yet it marked the beginning of modern chemistry and helped enable the industrial revolution, the development of oil-based fuels that power our cars and trucks (and whose emissions of carbon dioxide now threaten rapid climate change), and development of the fertilizers and pesticides that underlie modern high-yield agriculture such as the wheat and soybean crops of the Eastern Shore.
Modern physics (especially quantum mechanics) began more recently, in the 1920’s and 30’s, ultimately leading to semiconductor physics and the Information Technology revolution that is rapidly reshaping our lives. Modern DNA-based biology began more recently still, less than one lifetime ago, with most of its impact on genetic engineering and individualized, precision healthcare still to come. And now massive data collection and powerful computers are enabling artificial intelligence that, combined with robotic devices, promises to profoundly change manufacturing and many other human activities.
Such rapid change is hard for societies to adjust to, especially when job opportunities and career paths are affected. Some aspects of legal work are increasingly being automated, decreasing opportunities for lawyers. Some jobs in banking, manufacturing, and even aspects of medicine are on the verge of significant disruption. For example, in radiology, artificial intelligence systems can already interpret scans more accurately than most doctors can. Development of self-driving vehicles threatens both taxi drivers and truckers. Environmental concerns and the abundance of low-cost natural gas are rapidly eliminating coal mining jobs. At the same time, demand for wind-power technicians and solar power installers is growing rapidly.
A recent study of employment growth in Phoenix, Arizona, found that highly-paid jobs in industries where profits per employee were also high (think semiconductor manufacturing or data centers) grew only slightly over the past decade, while much lower-paid jobs in sectors with small profit margins per employee (think retail or health-care workers) accounted for most of the growth. In virtually every state, there are tens or hundreds of thousands of unfilled jobs for software programmers and cyber-security specialists, so K-12 schools are under increasing pressure to ensure that students graduate with the ability to program digital devices—a skill that quite recently was taught only to a small proportion of college students.
These currents of change are unlikely to go away; rather they are accelerating. At the same time there are growing disparities in opportunity and income between urban and rural areas, as well as residual racial and gender barriers to equal opportunity. Can society cope with these pressures and accommodate/adapt to change without serious implosions? Can we harness these new technologies, even on the Eastern Shore of Maryland, to improve prosperity and the quality of life for all? The Chinese benediction (or curse) seems appropriate: “May you live in interesting times!”
