Sometimes, as in the story of Gutenberg and the lens, a new innovation creates a liability or weakness in our natural toolkit, that sets us out in a new direction, generating new tools to fix a “problem” that was itself a kind of invention. Sometimes new tools reduce natural barriers and limits to human growth, the way the invention of air-conditioning enabled humans to colonize the hotspots of the planet at a scale that would have startled our ancestors just three generations ago. Sometimes the new tools influence us metaphorically, as in the robot historian’s connection between the clock and the mechanistic view of early physics, the universe imagined as a system of “cogs and wheels.”

Right of Way: Race, Class, and the Silent Epidemic of Pedestrian Deaths in America by Angie Schmitt

These precar neighborhoods have narrower streets than newer cities and buildings that are oriented toward them. As a result, they are inherently safer for pedestrians. That is not the case for cities like Fort Myers, Florida, and many of the other cities topping Smart Growth America’s list. A good rule of thumb is that if a city or state developed after the invention of air conditioning, it is likely to be a dangerous place to walk. Texas and Georgia, for example, have more than twice as many per capita pedestrian fatalities as Massachusetts, even though people walk at much higher rates in Boston than in Houston.40 “In most of these states, their built environments were constructed with Eisenhower’s Interstate Highways System as the model,” said Atherton of the National Complete Streets Coalition.41 Geoff Boeing, professor of urban planning at the University of Southern California, analyzed the street networks across the United States and found different patterns based on the “era” an area was developed.42 Boeing found that places that developed prior to 1940—central Philadelphia, Pittsburgh, Brooklyn, and the central cores of small towns and big cities alike across the country—have a high level of what Boeing calls “griddedness.”

But as mall culture went global, Gruen’s design became increasingly prominent in the downtown centers of new megacities. Originally conceived as a way to escape the harsh winters of Minnesota, Gruen’s enclosed public space accelerated the mass migration to desert or tropical climates made possible by the invention of air-conditioning. Today, the ten largest shopping malls in the world are all located in non-U.S. or European countries with tropical or desert climates, such as China, the Philippines, Iran, and Thailand. And while the mall itself would expand in scale prodigiously—a mall in Dubai has more than one thousand stores spread out over more than five million square feet of real estate—the basic template of Gruen’s design would remain constant: two to three floors of shops surrounding an enclosed courtyard, connected by escalators.

Technological systems gain their own momentum and become so complex and self-aggregating that they form a reciprocal environment for other technologies. The infrastructure built to support the gasoline automobile is so extensive that after a century of expansion it now affects technologies outside of transportation. For instance, the invention of air-conditioning in concert with the highway system encouraged subtropical suburbs. The invention of cheap refrigerated air altered the landscape of the American South and South-west. If air-conditioning had been implemented in a nonauto society, its pattern of consequences would have been different, even though air-cooling systems contain their own technological momentum and inherencies.

In the coal mining industry, the annual fatality rate per 100,000 miners dropped from 329 during 1911–1915 to twenty-five during 1996–1997.3 The reduction in injuries and fatalities across mining and manufacturing lifted the scourge of income loss and disability for thousands of households. Figure 15–1. Percentage of Employed Civilian Labor Force in Agricultural and Non-Agricultural Work, 1940–2012 Source: Table B-35, Department of Labor (Bureau of Labor Statistics), ratio linked back from 1940 to 1947. Just as the invention of air conditioning facilitated the flight of retirees to sunny southern destinations, so it also benefited the productivity, not to mention the comfort, of clerical and other white-collar workers. Productivity was estimated to have been raised by 25 percent among government typists during the 1950s as a result of air-conditioning, and it was rated as the chief boost to worker productivity by 90 percent of American firms in a 1957 survey.

Air-conditioning standards changed after 1976, with federal agencies all over the world requiring far more stringent cleaning and hygiene provisions for cooling towers and large-scale air-conditioning systems. In the case of Legionella, a new human disease had emerged in 1976, brought from ancient obscurity by the modern invention of air conditioning. At the CDC’s International Legionnaires’ Disease meeting in 1978, several particularly ominous facets of the bug were scrutinized. CDC scientists revealed that the organism could be found in tap water, shower nozzles, and other allegedly clean water sources. One tap water study showed Legionella could survive over a year inside pipe biofilms, emerging in wholly infectious form once the faucet was turned on full force.
