"With each interaction, Alexa is training to hear better, to interpret more precisely, to trigger actions that map to the user's commands more accurately, and to build a more complete model of their preferences, habits and desires. What is required to make this possible? Put simply: each small moment of convenience - be it answering a question, turning on a light, or playing a song - requires a vast planetary network, fueled by the extraction of non-renewable materials, labor, and data. The scale of resources required is many magnitudes greater than the energy and labor it would take a human to operate a household appliance or flick a switch. A full accounting for these costs is almost impossible, but it is increasingly important that we grasp the scale and scope if we are to understand and govern the technical infrastructures that thread through our lives. III The Salar, the world's largest flat surface, is located in southwest Bolivia at an altitude of 3,656 meters above sea level. It is a high plateau, covered by a few meters of salt crust which are exceptionally rich in lithium, containing 50% to 70% of the world's lithium reserves. 4 The Salar, alongside the neighboring Atacama regions in Chile and Argentina, are major sites for lithium extraction. This soft, silvery metal is currently used to power mobile connected devices, as a crucial material used for the production of lithium-Ion batteries. It is known as 'grey gold.' Smartphone batteries, for example, usually have less than eight grams of this material. 5 Each Tesla car needs approximately seven kilograms of lithium for its battery pack. 6 All these batteries have a limited lifespan, and once consumed they are thrown away as waste. Amazon reminds users that they cannot open up and repair their Echo, because this will void the warranty. The Amazon Echo is wall-powered, and also has a mobile battery base. This also has a limited lifespan and then must be thrown away as waste. According to the Ay

"Yves here. It's gratifying to see an article that uses as a central observation something we've pointed out: the first two generations of the Industrial Revolution led to a decline in living standards of most laborers, particularly in England. This piece looks at the parallels between the past industrial revolutions and the post-industrial revolution now underway, and anticipates that the results will include deglobalzation and more political shocks."

"Prosociality is endemic. In a common experiment called the social dilemma, anonymous subjects choose between a "defection" strategy that maximizes their own personal payoffs, and a "cooperation" strategy that gains them slightly less, but gives other members of the group substantially more. Up to 97% of subjects choose cooperation in some social dilemmas. Not surprisingly, researchers have found that the incidence of such prosocial behaviors declines as the personal cost of acting prosocially rises. We are more likely to be nice when it only takes a little, not a lot, of skin off our noses. But the scientific evidence demonstrates the vast majority of people will make at least small sacrifices to follow their conscience and help others."

"Regardless of its provenance, the idea that debt and war are the two primary ways to control a nation is a great insight into the current geopolitical situation, especially the rise of China. China has benefited from the world order created by American military dominance, with its 11 carrier groups and hundreds of military bases straddling the globe. China is motivated by national pride and economic self-interest to extend its sphere of influence, but many of its thinkers are ideologically opposed to replicating the American model, a militarism that they still call 'Western imperialism'. "

"new report from the Economic Policy Institute calls attention to the hardy perennial of how much America's corporate titans make: bosses of the top 350 firms made an average of $18.9m in 2017. That's a ratio of 312-1 over the median worker in their industries. Big bucks to be sure. And a big change since 1965, when the ratio was just 20-1. But what does it mean? And if there's a problem, what is it, exactly? What it means, as the EPI economists carefully document, is that the top US corporate chiefs are paid overwhelmingly with stock options, and their income fluctuates with the market. About 80% of the pay packet is in stocks, and the rise of 17% in 2017 after two flat years surely suggests that the top CEOs (not unreasonably) sensed the market peaked last year. So they cashed in. On the other 20% of the pay packets, no gains occurred"
