"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

"This has fundamental implications for how one thinks about current challenges. Globalisation and technological change are often portrayed as exogenous forces sweeping across the rich countries, inexorably driving up inequality and forcing workers to accept wage stagnation (and often less security) if they are to hold on to their jobs. Instead, the variation in country experiences shows how much institutions and policy responses matter to how these forces - themselves subject to human agency rather than God-given - play out in the job market and affect household disposable incomes. Wage-setting institutions clearly have a critical influence. The Belgian combination of wages indexed to inflation, collective agreements covering most workers, and a high minimum wage underpinned significant wage growth across the distribution. In Australia, the extension of collectively negotiated employment terms and conditions over much of the work force, together with a very high minimum wage, play a key role. By contrast, the remarkably poor earnings performance of the UK over the last decade is in a context where wage bargaining has become individualised."

Do we see ourselves as part of a larger "us," a "them-and-us," or an atomised "I"?

The problem for consumers up to now has been that the negotiated prices were unknown, or impractical to raise in court due to evidentiary rules. The general rule is that witnesses must testify to facts within their personal knowledge. Notably, if a consumer contests a medical debt collection lawsuit, someone from the hospital must testify that the price charged is reasonable and customary-an assertion that, with regard to chargemasters, involves shading the truth and is vulnerable to cross-examination.
